Specced for sun, salt and chlorine
Lightfastness is a testable property and deep shades fade fastest — we spec it deliberately rather than discovering it after a season on the beach.
Custom beachwear and beach towels, made to your design — cover-ups, towelling sets, and shorts in soft, lightweight fabrics, with worldwide delivery.
Collective Studio makes beachwear and towels in Narayanganj, Bangladesh, from 150 pieces per style and colourway: cover-ups, kaftans, beach towels, towelling sets, shorts and resort wear in cotton terry or viscose, shipped DDP worldwide, with 40–50 days' production after sample approval. About 70 days from order to your door by air. Lightfastness is specified rather than assumed, and beach and swim pieces are lab-dipped side by side so they match.

Beachwear gets treated as an easy category and it isn't — it's the one where colourfastness to light actually matters, because the product is worn in direct sun for hours at a time, often wet with salt or chlorine. A print that holds up fine on a t-shirt can visibly fade on a kaftan over one season in the Mediterranean. Lightfastness is a testable property (the standard test is ISO 105-B02), and it's worth specifying deliberately rather than assuming, particularly on deep or vivid shades, which fade most.
On fabric: cotton terry towelling is the obvious after-swim choice — actually absorbent, soft, and it reads as expensive, though heavier weights get bulky in luggage, which real customers notice. Viscose and rayon drape beautifully and are everywhere in resort wear, but they're substantially weaker when wet and wrinkle readily, so they suit a flowing kaftan far better than anything that needs to hold shape. Linen, gauze and seersucker are woven, so they are not cut on our floor; woven shirts and bottoms are sourced by our sister buying house, a separate company, under a separate order.
The practical advantage of making beach and swim with one partner is colour matching across different fabrics. Getting a swim fabric and a cotton cover-up to read as the same colour is difficult — different fibres take dye differently, so the same Pantone reference lands differently on nylon than on cotton. Doing both under one roof, with lab dips compared side by side, is how a coordinated set actually looks coordinated instead of nearly-matching.
| Piece | Fabric | Weight | How it is built | Check on the sample |
|---|---|---|---|---|
| Kaftan or long cover-up | Viscose jersey | About 140 to 200 GSM, the range our fabric guide gives for modal and viscose from bamboo | A loose cut with room through the body, so the seams are not under strain when the fabric is wet | Drape, length and wrinkling after a wash; viscose is weaker wet, so the care label needs gentle-wash wording |
| Towelling cover-up or robe | Cotton terry towelling, with loops on both faces | Made to the weight you specify, confirmed on the sample | A relaxed fit; heavier terry adds bulk at seams, hems and pockets | Bulk when folded and drying time; a robe sold in Great Britain may need a nightwear label (see the FAQ below) |
| Terry polo or towelling top | Cotton terry towelling | Made to the weight you specify | Cut and sewn like a polo or tee, with the loops on the face as the texture | Collar and placket shape after a wash, and shrinkage on the first wash |
| Beach and lounge shorts | French terry or cotton terry towelling | About 140 to 220 GSM for light shorts, 280 to 400 GSM for sweat-style shorts | Elastic waist, usually with a drawcord, as on our shorts | How the waistband recovers after the shorts have been worn wet |
| Matching swim piece | Nylon or polyester with elastane, lined | Specified with the swim fabric | Cut and sewn on our floor as swimwear, a separate construction | The same colour reference lab-dipped on both fibres and compared side by side |

Launch or extend a beach range without a big commitment.
Terry for absorbent after-swim, viscose for drape — each with an honest trade-off we'll walk you through.
Different fibres take dye differently. Making beach and swim together with lab dips compared side by side is how a set actually matches.
Lightfastness is one of four colourfastness tests worth knowing for beachwear, because a beach piece meets sun, sea water, pool water and sweat, often on the same day. Each is a separate ISO method, run on fabric dyed to your production shade, and each is run per colour. Retailers with a technical standard usually name the tests and the minimum grade they accept, so ask your buyer for that list first, then tell us which tests to arrange before bulk ships.
Two practical points. Test the bulk shade, not the lab dip, because the rating belongs to the lot that will be sold. And watch staining as well as fading: the sea-water and perspiration tests also rate how much colour moves onto a fabric placed against the sample, which is how a deep-dyed kaftan that marks a pale swimsuit is caught before it reaches a customer.
| Test | What it simulates | Where it matters on a beach range |
|---|---|---|
| ISO 105-B02, light | Daylight, from a xenon arc lamp; fading is compared against blue wool references | Every beach piece, and deep or vivid shades most |
| ISO 105-E02, sea water | Immersion in a salt solution, then drying; rates colour change and staining | Cover-ups, kaftans and shorts worn into the sea, and the swim pieces they are sold with |
| ISO 105-E03, pool water | Chlorinated water at pool-disinfection levels. The standard sets 50 and 100 mg/l active chlorine for swimwear and 20 mg/l for accessories such as beach robes and towels | Towelling robes at the 20 mg/l level; swimwear at the higher levels |
| ISO 105-E04, perspiration | Human perspiration, in two test solutions; rates colour change and staining | Pieces worn against hot skin all day: kaftans, tops and shorts |

A beachwear quote is fabric weight and fibre first, then the dye work needed to hold colour in sun, then quantity.
Cotton terry and viscose are bought by the kilo at different prices per fibre. Terry is also heavy, so a towelling robe carries more cloth cost and more freight weight than a viscose kaftan of the same size, and that difference follows it into the DDP price.
A towel is priced almost entirely by weight: GSM multiplied by its dimensions sets how much cotton it contains. A large, plush beach towel therefore costs more per piece than a smaller or lighter one, and the extra weight follows through to the carton and the DDP freight.
Holding colour in direct sun requires dyes with higher lightfastness ratings and, ideally, a test to ISO 105-B02 on the production shade. The test is a cost per colour, and deep or vivid shades need the better dye classes, so a saturated palette costs more to get right.
A coordinated set means the same colour dyed on two fibres, nylon for swim and cotton or viscose for the cover-up. Each fibre is its own lab dip and its own dye lot, so a matched pair is two dye minimums per colour, not one, and the matching work is extra lab time.
Every colourway is a separate dye lot and a separate 150-piece minimum. Pattern, grading and sampling costs are spread across the order, so the unit price at 150 carries all of it and steps down as a style passes roughly 500 and 1,000 pieces, then flattens.
Cover-ups, kaftans, shorts, towelling sets, bucket hats and tote bags, plus swim itself, which is a different construction discipline and priced separately. The fabrics we cut for the beach are cotton terry towelling and viscose: one absorbs, the other drapes, and neither is meant to hold structure. Linen, gauze and seersucker are woven and are not cut on our floor; if the range also needs woven shirts or bottoms, those go to our sister buying house, a separate company, on a separate order. What we would steer you away from is treating beachwear as summer versions of your main range: the fit is looser, the seams are usually flat rather than overlocked, and garments are expected to be worn wet, sandy and washed often. Those are construction decisions taken at pattern stage, not finishing touches added later.
Yes, some fading will happen, because every dyed textile loses colour under sustained UV; what you control is how fast. Beachwear is where it matters most, since it is worn in direct sun for hours, often wet with salt or chlorine. Three decisions set the pace. The first is dye class: on cotton we use reactive dye by default, which bonds with the fibre, whereas pigment dye sits on the surface and fades faster. The second is shade: deep and vivid colours fade most, so a saturated palette needs better dye classes and costs more. The third is proof: lightfastness can be tested to ISO 105-B02 on the production shade, charged per colour, and we can arrange it if a retailer requires a rating. If the range includes matching swimwear, polyester holds colour against UV far better than nylon, though nylon has the softer hand. Tell us your market and palette at quote stage, and we will specify dye and testing to suit.
Two quite different propositions, and most beach ranges can use both. Towelling is looped cotton: absorbent, soft, and increasingly used for cover-ups and co-ord sets rather than only for towels. It is heavier and reads as a considered resort piece, but it is bulky in luggage and slow to dry, so it suits the after-swim moment more than a full day of wear. Viscose drapes better than almost anything at this price point and feels cool and fluid, which suits kaftans and loose cover-ups, though it wrinkles readily and loses strength when wet, so it wants gentle care and a pattern that does not strain the seams. For a first beachwear range, most brands do well with towelling for one or two hero pieces and viscose for the flowing styles, and we will walk you through the trade-off on each before you commit to fabric.
In the same order, yes, though they are different disciplines and priced separately. Beachwear — cover-ups, kaftans, shorts, towelling — uses cotton terry and lightweight knit fabrics and relatively simple construction. Swim uses recovery fabric, usually a nylon or polyester elastane blend, with linings, gripper elastic, adjustable hardware and flatlocked or bonded seams, and the pattern has to be cut for a fabric that stretches and returns. That means swim carries a longer sampling stage and a higher unit cost. Running them together makes sense commercially because the customer buys both and you can share a print or colour story across the range. Tell us at quote stage if you want a matching print, because getting the same colour to read identically on two different fabrics is a decision made at dyeing.
If it is sold in Great Britain as a robe, plan for one. The Nightwear (Safety) Regulations 1985 count dressing gowns, bath robes and other garments of a like nature and use as nightwear. Adults' nightwear must carry a label: KEEP AWAY FROM FIRE in red letters if the fabric does not meet the BS 5722 flammability requirements, or LOW FLAMMABILITY TO BS 5722 if it does. Children's nightwear must normally be made of fabric that passes that test, but cotton terry towelling bath robes are an exception: they carry the label instead. A kaftan or cover-up sold as daywear is a different product, and whether your beach robe counts as a bath robe depends on how it is designed and sold, so check it with your safety adviser. Send us the wording with your label artwork and we sew it in during production, inside the neck or next to the size label, where the Regulations put it.
The cotton pieces can. Towelling cover-ups, robes, terry polos and shorts can be knitted from organic cotton yarn and made in our GOTS-certified facility (RSC 9687), with our scope certificate on request and a transaction certificate issued for your order if a stockist asks for one. Viscose is different: it is regenerated from wood pulp, not grown, so a viscose kaftan cannot be sold as organic. The useful check is where the pulp comes from, such as certified forests (FSC or PEFC), which our sustainable fabrics guide explains. A matching swim piece is nylon or polyester with elastane; recycled nylon is the recycled option, and a recycled claim on its label needs GRS or RCS documentation for the lot, which we do not hold ourselves. GOTS has two label grades: 'organic' needs at least 95 per cent certified organic fibre, 'made with organic' at least 70 per cent, so check each piece's grade before labels are printed.
