Because my bra size has recently changed and I have accepted that my weight is not likely to change dramatically in the near future I went through drawers, and storage today and listed my barely used bras on a clothing sale site. It's embarrassing to say, I listed over 30. Pre mustachuan days I thought nothing of buying a new sexy bra and panty set before a special date night. At my new size I have a smooth black, a lace black, a smooth off white, a lacy white one, a red one and 2 fancy speciality bras. All bought with combination of bogo sales, coupons and gift card, so no money out of pocket. I try to make sure when I buy panties that they match/coordinate, but will not pay more just to match.
Some people see bras as simply foundation, and do not care if they are pretty, sexy etc. just as long as they fit well. I cannot stand to wear a plain Jane boring one. When I was thinner I only bought Victora Secret, as they seem to be the best value for the money-frequent sales, coupons, and the almost always have a coupon for free panties as well. Now I buy only from Cacique, who is owned by VS.
