Wonderbra is a brand that knows how to cater to women. I love love love their bras especially the strapless and the new perfect plunge.
I would really suggest buying one. There is usually some sort of offer going on as well. I think they are great to wear with recent fashion. Many dresses lately are low cut or have some sort of mesh cut out at the front. I know my first thought when I try one of those dresses on is 'what bra can I actually wear with this?'. Wonderbra has solved this problem.
