J.Crew Factory Pleated Front Blouse Black Sleeveless Sz 4

J. Crew Factory Structured Pleated Front Black Sleeveless Crepe Top Women's Sz 4 Good pre-loved condition. No holes or stains. Normal wear on fabric. Back of neckline looks like it has a piece of white fabric or thread sewn into the stitches. Was afraid to pull on it so I left it alone. It's not bad but you can see a little sliver of white there. May be removable but I didn't want to possibly wreck the fabric. See photo. Approximate measurements for flat lay garment unstretched pit to pit 18" length from shoulder to hem 25"
