shellybelly: buy all those adhesive, hollywood tape etc things and TRY them with ur dress. it mighty get costly, but u need to figure out wat works for u.
go to bra shops and myer, and take ur dress with u so u can try the dress on with the bra.
just a suggestion:if u dont end up finding the perfect bra, u could always wear a plain strapless, and if the bit in the middle shows where ur cleavage is, then stick a jewelled brooch right in the middle. it make ur dress sparkle and it'll hide the the bra strap in the middle. always work with what u got.
i want smaller boobs too lol
and omg i wanna see that $300 bra too!
