What a fun dress! It looks really cute on. This mid-century dress is a nice striped fabric of cotton and rayon. The stripes are fun and flattering. The dress has a super cute retro pull that opens and closes the zipper at the front of the dress. The collar is really big and fun.
The dropped large pockets are really handy to carry a cellphone! The style is a shift style, but one picture shows it belted with a ribbon. (ribbon not included). This dress is super comfortable and could be worn to work, school, lunch, coffee, or just around the house!

The union label indicates 1960s. The brand is Sears. Could be a vintage nurses uniform.
