Labels for Swimwear and Lingerie: Soft, Resistant and Comfortable

Swimwear labels and lingerie labels sit closer to the skin than almost any other label in fashion. They are worn wet, stretched, rubbed under straps and washed by hand or on delicate cycles, often with chlorine, salt, sun cream or sweat in the fabric. A label that feels fine in a sweatshirt can scratch in a bikini top or show through a fine bra cup. This guide explains how to choose soft labels for underwear, bras, swimwear and shapewear: the right materials, edges and folds, when to go tagless, where to place the information and what the care label should say.

What swimwear and lingerie labels have to withstand

Before choosing a label type, list the conditions it will meet in real use:

• Chlorine and salt water: pool water and seawater attack weak dyes and some fibres. Colours can fade or bleed, and poorly sealed edges loosen faster when wet.
• Sweat and body oils: lingerie and activewear-style swimwear absorb perspiration every time they are worn. The label must keep its print legible and must not stiffen.
• Sun cream and UV: creams and oils can stain light labels, and sunlight fades unsuitable inks.
• Stretch: elastane fabrics stretch in every direction. A rigid label sewn into a stretch seam restricts the seam or puckers it.
• Friction and visibility: straps, cups and briefs press the label against the skin. Thick labels or hard edges are felt immediately and can show through thin or moulded fabrics.

The answer is a combination of thin, colourfast materials, sealed soft edges and smart placement. For general comfort principles, our article on soft labels for T-shirts is a useful starting point; this guide focuses on the extra demands of intimate and swim products.

Soft label materials for underwear and swimwear

Printed satin

Polyester satin printed with a durable ink is the most common choice for lingerie care labels. It is smooth on both sides, thin and flexible, and it takes small multilingual text well. Choose a soft-hand satin quality and ask for print that is tested for repeated washing. Satin is also used for the brand label in lingerie, with a printed or woven logo.

Fine woven satin and high-definition damask

For a woven brand label, a satin weave feels softer than taffeta, and a fine high-definition damask keeps small lettering sharp while staying relatively thin. Keep the label small and the design simple so that it does not become stiff. A softening finish can further reduce the hand feel. See our woven labels for qualities and folds.

Soft polyester and nylon tapes

Thin printed tapes are useful for size and care information in swimwear. Nylon taffeta is very durable but crisper, so it suits areas away from direct skin contact, such as inside a lined section or a side seam that is covered.

Tagless heat transfers

For many swim and lingerie products, the most comfortable label is no sewn label at all. A low-temperature heat transfer printed directly on the fabric carries the logo, size and short care information. Transfers for stretch fabrics are designed to move with elastane without cracking. Our heat transfer labels guide explains transfer types and application.

Edges and folds that stay comfortable

The edge of a label is usually what irritates, not the face. For intimate products, specify:

• Ultrasonic-cut edges: the fibres are sealed cleanly and softly, without the hard bead that a hot knife can leave.
• Small sizes: lingerie brand labels are often 10–15 mm wide; care labels around 25–30 mm wide.
• Folds that hide the cut ends: a centre-fold or loop fold sewn into a seam keeps the cut ends inside the seam allowance. A flat label stitched on all four sides lies flat and does not flip up.
• No fused or laminated stiffeners unless the label is placed on the outside.

Whichever fold you choose, ask for a physical sample and sew it into a real garment before approving the order: a fold that looks neat on the desk can behave differently in a stretch seam.

Where to place labels in swimwear and lingerie

Placement has more influence on comfort than any other choice. Typical positions are:

• Bras: on the side wing or at the centre back near the hook-and-eye closure, sewn into the seam, never under the underwire channel or in the cup.
• Briefs and thongs: in the side seam or at the back waistband seam, flat and small. Many brands print the label inside the back instead.
• Swimsuits and bikinis: in the side seam of the bottom, inside the lining, or printed as a transfer on the lining fabric. Avoid the neck and straps, where the label would show when worn.
• Swim shorts: a woven or silicone brand badge outside on the leg or waistband, with a care label inside the side seam or in the inside pocket.
• Shapewear and seamless garments: tagless heat transfer inside, because any seam is visible under clothing.

Remember that EU fibre composition information must be durable, easily legible and accessible. A label that is cut off by the wearer still has to have done its job at the point of sale, so keep it reasonably comfortable rather than making it so annoying that it is removed immediately. More placement ideas are in our guide to clothing label placement.

Care content for swimwear and lingerie labels

The fibre composition is mandatory under Regulation (EU) No 1007/2011 and must be given by weight percentage with the official fibre names, for example "80% polyamide, 20% elastane". Lined swimwear and padded bras often have several components, so list the composition per part, such as outer fabric, lining and padding. Non-textile parts of animal origin must be declared where relevant.

Care symbols follow ISO 3758, in the order washing, bleaching, drying, ironing and professional care. Typical care content for these products includes:

• hand wash or machine wash at 30 °C on a delicate cycle, often in a laundry bag for bras;
• do not bleach;
• do not tumble dry, dry flat or line dry in the shade;
• do not iron, particularly for moulded cups and elastane-rich fabrics;
• a short text such as "rinse in cool fresh water after swimming" for swimwear.

Swimwear and lingerie are sold across many markets, so care labels often need several languages. A booklet care label keeps long multilingual text compact. Our guide to care label symbols explains each symbol in detail.

Colour and branding

Lingerie brands often want labels in skin tones, black, ivory or seasonal colours that match the fabric. Woven labels take their colour from the yarn, so they hold well in chlorine and salt water; printed labels depend on the ink and the base tape, so ask for a colourfast print system. Keep fine lines thick enough to stay legible after repeated washing. Gold or silver lettering can be woven with metallic yarn for a premium detail, used sparingly for comfort.

Ordering labels for swimwear and lingerie

Send us the fabric composition, the care instructions, the languages you need and photos of the garments with the intended label positions. Our designers prepare a digital proof typically within 24–48 h, and physical samples are available before production so that you can wear-test them. The minimum order is typically 1,000 pcs per design, production takes typically 10–20 working days after approval, and we deliver across the EU. All labels are produced in our own production in Bulgaria, with OEKO-TEX Standard 100 certified materials available for products worn next to the skin.
