I practically never buy matching sets, poor DH I have other lingerie though

I'm like Astrid, I choose my underwear based on what clothes I'm wearing - what bra looks best under that top, what knickers don't show through my skirt, or over the top of my jeans etc etc.

Ryn, it's funny you should mention UK sites for getting big bras - I saw a program on SBS the other night that said British women are recorded as having the biggest breasts in the world!
