Striped dress, no size

Striped dress, worn a couple times but just got another linen striped dress in same colors and don’t need both. Blue with white stripes, unknown fabric (perhaps cotton, maybe some poly in there too…feels good like cotton or linen). Beautiful lace at collar. Mid length sleeves. Nice stitching detail around pockets. Great condition. Only tag on dress says “mordenmiss”. I typically wear a small, 6 or 8. I’m 5’9”
