I bought a leather boat neck dress from Bershka a while ago. Its perfect in every way, but its sleeveless and comes down quite low at the sides and its also a bit too big round my bust. I'm a classic pear shape,. Ideally I could do with a black bra which shows at the sides as little as possible and also boosts my bust by at least one size. Any ideas welcome. I'm going to be in London on Friday so could maybe go to John Lewis or similar but have limited time cause I am there for work.
