I have never worn a bikini for various reasons not least my difficulties finding a comfortable bra.
If you know of any bikini tops that fit like the Uniqlo wireless bra please point me in that direction.
I am a 30d in bras but struggle to put swimwear over the top like a vest so it has to do up like a bra (or ideally a front zipped crop top, like to Sainsbury's bra tops, but they are few and far between).
