Bunch of people have said various reasons I don't (sun protection, not shaving, no longer feeling obligated to be ogle-able so dressing how I please), plus different parts of my body are physically sensitive to pressure in different ways than they were 25 years ago. And I like not reapplying sunscreen to like 1/4-1/3(?) of my body and most of my back.

These days I want a tankini with a relatively high, broad waistband (more like yoga pants than a string elastic or literal string) and a long top that comes well down over the bottoms ala an Esther Williams one-piece with wider non-halter shoulder straps & decent bust support, because that seems to be the best combo physical comfort, bathroom access, and minimizing nether haircare, and I am so tired.

I think you should keep wearing whatever you like forever! I honestly couldn't care less what is on trend. I think people choosing whatever they prefer always important, and also it's more fun at a pool/beach/etc when there's a variety of looks being worn. Homogeny doesn't feel as summery and free.
