Calvin Klein sheath dress size 12 , black and white plaid mix

This dress is a Calvin Klein, size 14, sheath dress with a zipper back and features a small faux patent leather belts with buckle and elastized back. Has an interesting positive and negative style plaid design Measuring 21 in from pit to pit when laid flat. It appears there is slight discoloration on the chest near the very center however the pattern plays with my eyes and I can't tell if it's actually there or just the lighting most likely will come out if it's sent in for dry cleaning.
