Como tank top pair with black lace trim. One grey, one dark turquoise. Size US S

Como tanks, selling as a pair, one grey with black lace trim and piping, the other dark turquoise with black lace and piping. Wear alone or under a suit jacket. No fabric content or care tags, but my best guess is polyester. I would wash on a delicate cycle and hang to dry, cool iron. Never worn, excellent like new condition. Size US S
