What the AI looks for in Women's Bikini Tops
- Sizing system
- Above about a D cup, use band-and-cup sizing and start from your bra size. S/M/L sizing can't fit band and cup separately, so it gives poor support at larger cups.
- Band does the work
- The band should sit level and snug without relying on the neck straps. Halter-only support strains the neck and lets the top shift.
- Strap adjustability
- Look for adjustable or convertible straps, with crossback options for activity. Adjustable straps let you fine-tune fit and keep the top secure in water.
- Cups and lining
- Choose a fully lined top. Removable pads should have proper pockets so they don't fold or migrate. Loose pads crease and shift when wet.
Brands that matter
- Freya: Underwire bra-sized tops in a wide cup range.
- Panache: Supportive moulded cups for fuller busts.
- Curvy Kate: Bra-sized swim tops for D+ cups.
- Seafolly: Fashion triangles and bralettes for smaller busts.
- Speedo: Sporty crossback tops for swimming.
What to avoid
- Tie-only bandeaus for fuller busts or active use.
- Unlined tops in light colors.
- Buying bra-sized tops by S/M/L guesswork.
Questions
Is my swim cup size the same as my bra size?
Usually it is close with bra-sized swim brands. Swim bands can run slightly firmer, so check each brand's size guide.
