PINK Bras

I was wondering how long does Victoria’s Secret PINK bras last? I’m in need for some new bras which I only get from the Victoria’s Secret side, but I was thinking of buying the ones PINK have on sale for $20.00 since that is a really good deal. I’m just kinda iffy on buying them because the ones I have now were more expensive but have lasted me for five years and I heard that PINK bras can be cheaply made. I’m a 32C if that helps? Thanks in advance!
