Vintage Valentino blouse

I have loved this vintage Valentino blouse for years, but it's time to share it with someone new. I simply haven't worn it enough. it is in perfect condition. gorgeous metallic thred. It is labeled a 4, but it's a small 4, closer to a 2 or 0 (another reason for its arrival on posh). if it were a bra, I think it would be a 32-34 A or B.
