Basic white button up from Madewell. Oversized fit. Side slits give a bit extra flare. Perfect for jeans or yo throw on with shorts and a swimsuit! Not sure of the fabric content as I must have cut it out. Worn and washed once. I have two many white button ups and I’m trying to scale it back 😬 Pit to pit is 24” Under pit to bottom of sleeve 16 1/4” Collar base to end of sleeve is 28” Length of back is 29” Length of front is 27 1/2”
