Magic Blue and Purple Plaid Sleeveless Blouse

adorable vintage tank top blouse! I love the double blue with red, I'm honestly crushed that this is like slightly too small for me label size is a vintage 18, it is pretty close to a modern 18. pit to pit laying flat measures just over 22in, ans length from shoulder to bottom is 21in item is on brand new condition with tags. the tags are still attached and I couldn't find any signs of it aging poorly.
