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.
I own all three bras in the above picture. I have to say the strapless bra is the best I've ever had. Unlike most strapless bras which give you that weird slouchy I'm not even sure what to call it. But you know what I mean.
My only problem with them is after wearing it all day it can start get painful. I rarely have this problem though because I only really wear them for a special occasion and nights out.
If you love low cut tops or strapless items I would definitely add one to your underwear drawer.
