"sculptured 3-dimensional undercup" reminds me of corsetry, a widely adopted technology generally replaced by bras

Which annoys me, actually, because the most supportive garment I've ever owned is the bodice from my Renfaire costume (30 years later and it still looks almost good as new, too!) and I'd wear it all the time if I could

Fun fact the inspiration was those rubber flying rings

Weird that something designed by sewing two hankies together became the dominant over the shoulder boulder holder tech.
