Made of “Lastex”. I looked it up – it was an elastic yarn invented in the 20s, I think? It was a rubber core wrapped in wool, cotton or silk, and later rayon. If I had to guess, this is a cotton version. It’s very soft.
The fabric almost has a velour type quality to it.
No lining or cups
Knot detail at the bust
Swim dress style that you see in almost all the vintage swimwear
Doesn’t even look like it has ever been worn!
Still has good stretch
The first name in swimwear – Jantzen! I am OBSESSED with the diving girl logo.
