Handmade lace butterfly sleeved top!

30s? handmade lace butterfly sleeved top! Not exactly sure what style of top this is called but it is so so adorable. Honestly could be from the 1970s, the crochet work is hand done. My gut says 30s but no way to know 100% It has several strips of what looks like handmade lace. The top as a whole appears to be entirely handmade actually. It has the tiniest little pleating! It has two really small pin size stain stain marks, and that is literally it. It is in fabulous wearable conditio
