Act III Vintage Sailor-Vibes Zip-Up Shirt

Brand-Act III Quality- Quite good I bought this a few years ago at a vintage shop. I have only worn it about three times. It's super cute, and I've never seen anything like it before or since. The size is not marked on the tag, but I am guessing it's around an 8 or 10? I am 5' 11" and about 155lbs. I usually wear a medium for tops and it fits. It's just a little snug.
