Color block Blouse Black, White, Beige

Worn once and I realized it’s hard to wear appropriately to work unless I wear a jacket all day (I work at a school so that’s unnecessary). Is a little bigger than expected for an XS. Meant to fit loose so it can probably be worn by someone up to a size large, if they want it tighter. There’s a keyhole-type opening in front and an interesting back detail. Narrower at top than bottom, as it is meant to hang freely. Reaches below my waist (I’m 5’2”).
