Vintage 50s Blue Alix Miami Floral Miracle Length Swimsuit - One Piece Bathing Suit
No size tag - please see measurements - Model is 5'1" with following measurements: 31/24/34 - Suit was too big, more so in stomach than bust, 32" bust would be okay.
The top has elastic in the back, 13. 5" unstretched, stretching to 17" so I imagine a 34" bust would be fitted. The bottom half has little strips of vertical elastic (the shirring), this might be the "miracle length" aspect...maybe for tall persons? The straps have 3 buttons, allowing more length. Hips are 38" . Waist is 29". Each leg hole is approx 21" around. 29" from top of shoulder to crotch, extra buttons allow 2 more inches.
Shelf bra in good shape. Back metal zipper.
Flaws: See all photos, inside the suit there is a patch repair on the bottom. The shirring/elastic may be loosened/stretched. Overall mild fade and a few stitch marks along one side.

This item is sold from an excellent, highly rated vintage boutique.
