Bikini Care 101: How to Make Your Designer Swimwear Last for Years
A well-made bikini is an investment. A Vitamin A EcoRib set, an Acacia crochet top, a Hunza G crinkle one-piece — these are pieces designed to last for years if you treat them correctly. The bad news is that most of us are unknowingly degrading our swimwear within the first month. Here is everything you need to know to protect your collection.
The First Rule: Rinse Immediately
Salt water, chlorine, and sunscreen are the three primary enemies of swimwear fabric — and all three begin their damage within minutes of exposure. The single most important care habit you can build is rinsing your swimwear in cool, fresh water immediately after use. Do it at the beach shower, the outdoor shower at your hotel, or the moment you get home — but do not leave it to later.
Chlorine in particular is aggressive: it breaks down elastane (the elastic fibre in all swimwear) and causes colour fading and fabric degradation from the inside out. Even brief pool exposure compounds over time. Rinsing immediately removes the majority of the chlorine before it can set into the fibres.
Hand Wash Only — No Exceptions
Machine washing is the fastest way to destroy designer swimwear, full stop. Even on a delicate cycle, the agitation stretches and distorts elastane, loosens structure, and causes fabric pilling. For your Vitamin A EcoRib and BioRib pieces, machine washing is explicitly contraindicated — their recycled nylon construction is sensitive to mechanical stress and will lose its shape and recovery significantly faster.
The correct method: fill a clean sink or basin with cool water and a small amount of swimwear-specific or baby-safe detergent. Submerge the piece, gently work the fabric between your fingers for 2–3 minutes, and rinse thoroughly in cool water until all soap is removed. Do not soak for longer than 30 minutes and never use hot water — heat is a primary cause of elastic degradation.
No Spin, No Wringing: How to Remove Water
After washing, do not wring or twist your swimwear to remove water — this stresses the fabric and distorts the shape. Instead, lay the piece flat on a clean, dry towel, roll the towel up with the swimsuit inside, and press gently. The towel will absorb the excess moisture without mechanical stress. For Hunza G's crinkle nylon pieces, this step is especially important: the crinkle texture is a function of the fabric's construction and will maintain itself correctly only when treated gently — wringing will distort the crinkle pattern in ways that are difficult to reverse.
Flat Drying Is Non-Negotiable
Hanging swimwear to dry causes the weight of the water to stretch the fabric downward, permanently distorting the shape — especially in tops with cups or underwire, and in one-pieces where the torso length can change significantly. Always dry flat, in the shade. Direct sunlight accelerates UV degradation and fading — ironic given where swimwear spends most of its life, but the controlled drying environment matters.
For Acacia Swimwear's crochet pieces, flat drying is essential to maintaining the geometry of the crochet pattern. Reshape the piece by hand while damp and lay it on a flat towel away from direct sunlight and heat sources.
What Ruins Swimwear Fastest
In rough order of damage severity:
- Sunscreen and self-tanner: Chemical sunscreens (especially those containing avobenzone) react with chlorine to create permanent orange or rust staining on light-coloured fabrics. Always apply sunscreen and allow it to absorb for 15–20 minutes before putting on your swimsuit, and opt for mineral sunscreens where possible.
- Chlorine: As above — cumulative damage that destroys elastane and fades colour. Rinse immediately, every time.
- Heat: Hot tubs, dryers, direct sunlight while drying — all degrade elastic fibres significantly faster than cool or room-temperature environments.
- Rough surfaces: Pool edges, natural rock, textured walls. Beach Bunny sequined pieces are particularly vulnerable — the sequin backing can snag and pull on rough surfaces, so always sit on a towel and handle with care.
- Machine washing and spinning: As covered above — simply don't.
Storage: End of Season Care
At end of season, store clean, fully dry swimwear flat or loosely rolled in a breathable fabric bag — never compressed at the bottom of a drawer or stored in plastic, which traps moisture and promotes mildew. Keep pieces away from direct light to prevent colour fading during storage. For Hunza G crinkle nylon, storage method matters less than for other fabrics (the crinkle is part of the material's structure and will not be lost to gentle compression), but clean and dry remains essential.
