Land n Sea began producing casual clothing in 1958, so this could be their early work, or even a nod to the 50s, from the 80s. The fabric is summer weight. This blouse has a bat-wing cut. The cuffed sleeves CANNOT be rolled down...which makes me think it is an 80's nod to the 50s. No darts, which means less tailoring, so again...80s? Its a large size, which is great, and hard to find. I have had this since the 80's or 90s, and found it thrifting. Its too big for me, but anything Rockabilly, is a keeper for me. Now you can enjoy it. No flaws, that I can see. Go ONLY by measurements!
Bust: 46"
waist: 42"
length: 24. 5"
shoulder span: 18"...there is no seam, so this is a guess
