I just buy undies all the time. I love them. I think I have so many that they stay in good condition and I don't seem to throw out. I am extremely fussy about the fit. If I get muffin top I don't buy them. If undies fit me perfectly, I feel great wearing them.
I worked out the other day, that I have a lingerie set that's at least 6 years old! How's that for quality! The only reason I know this is because it was given to me by an ex, and so I know how old I was when I got it.
I often get knickers for presents because my mum and friends know that I love them so much, hence I have soooo many.

I am designing a lingerie range ladies, so I would love to hear what you like/love/hate about underwear that's out there.
