NWT Rag & Bone Dress Vest - Size S

Unworn NWT Rag & Bone Dress Vest Its a Size S - so about a 38 shirt collar size i guess *This is a heavier material. It can fit under a blazer or suit jacket, but i'tll be tight and hot. This is meant to be worn kinda just over a shirt, trendy style.... not as a formal vest as part of a suit and tie setup .
