Vintage 80s Women’s Shirt White Red Polka Dots Button Up Blouse Medium/Large? This is a great little vintage 3-button shirt with a bold geometric style in white with big red dots. The only tag is the brand, which is called “Sportsgear,” and which Google is telling me was made in the 80s and early 90s. I would bet that it is 100% cotton based on the feel of the fabric. It is probably a medium or a large with a boxy fit – please see the measurements in the photos. This could be a fun top for a Fourth of July party Key words: vintage, vtg, retro, geometric, bold, colorful, blouse, 80s, 1980s, eighties, rockabilly, dots, circles, polka dots, 4th of July, Fourth of July
