Vintage pinup summer dress tie straps size 4-6

Blue and white stripes fitted pinup dress, fabulous condition for how old it looks and for the decade I've been dragging it around. No tags. No indicated size or fabric contents but my measurements are 5'6 132lbs bust 34 underbust 30 waist 26 hips 36 and fits me like a glove, fits like a 4, room for a slightly bigger bust than mine. Goes down to my knees. I'd recommend dry cleaning? I think I threw in the wash at some point and the inside slip is wrinkley. Zips up in the back. Straps tie so you can kind of adjust. Not a dress to move around too much in lol, legs can't spread far. No stretch to this. Comes from a home with a dog and cat so folks with allergies beware.
