Vintage Susan Lawrence shirt, size medium. 
pit to pit is 17 inches but it is very stretchy. Would fit a medium to large. Length is about 22 inches.

it is mostly polyester but I still love the vintage vibe and fit. Scoop neck, but not too low cut. Immaculate condition 

I would personally pair this with a high waisted pair of dark jeans and black cowgirl boots. I would tuck in the shirt and wear a belt with it. There are so many ways to style this piece, it's the perfect staple shirt for your wardrobe. I highly debated on keeping this.
