Brand new, never been worn!

I purchased this bustier at BHLDN to wear under a beautiful BHLDN topper and skirt. (It can be worn strapless or with small removable spaghetti straps, included). A few months later, closer to my wedding, I decided I needed to size up. So I purchased another one and couldn't return this one to BHLDN given their 30-day return window. This one is brand new, in the dress bag, with all tags, never been worn. (The photos of me in the ad are in my size 6 top, which I'm keeping. This listing is for the size 4 never been worn--I included photos to give you a sense of what it looks like on).

(NOTE that this is just the bustier, not an entire dress!)
