Light Peach-Colored Lingerie Set

Beautiful and feminine lingerie set, never been worn, new with tags. The top (maybe around 34B?) has a clasp closure in the front, and a neat keyhole type design in the back. Comes with matching thong. My dear sweet boyfriend got this for me as a gift, but it's not the correct size. The store he bought it from doesn't do returns or exchanges. I'm knocking $20 off of the original price because I believe the quality is worth more like $25, not $45.
