Blue Rain romper; floral navy blue and white

Cute romper with satin-y feel. Light and flowy. Discoloration under arms as pictured, could probably be treated with stain remover. Slightly loose threading at base of zipper as pictured. It’s not noticeable when it’s on and zipped up so I’ve never bothered to fix it. Otherwise great condition. I’m 5’7” wearing like 3 inch heels in the last pic. Labeled size medium but I’d say it’s more like a small idk
