Neoprene thongs
 

Has anyone one tried wearing the new Slutty Girl thong? it has a flat style girl look front and is made in white neoprene. I am thinking about ordering one.

thanks

Neoprene is more like leather than Lycra or rubber. It is thicker and structural, where Lycra of rubber stretch and conform to the body's shape Neoprene will impose it's own shape over the body.
If you are certain you want a fem look then go for it.
The alternative is a butch male look as expressed here:

Consider as a synthetic alternative to leather.

Neoprene suit
 

The one I am looking at is at koalaswim.com
It is a feminine look suit but there something manly about it too.

I had the Neoprene Koalaswim Skin Diver bikini in Medium, which is similar but black with a Brazilian rear. It is flat in front with a bit of room underneath between front & back, so everything goes underneath comfortably. Michael recommends size Small for a real femme look, so I bought that this year and I like the snugger feel. With Neoprene, I think a Brazilian rear would be more comfortable than a thong, so that's my choice. I can wear it at any crowded public beach, the completely flat front is more acceptable than a big bulge, and I look manly in it. The photo is my new size Small suit.

I actually prefer Spandex BBlair Thong Gaffs for a flat femme look, I have posted about them before but have new photos and a new source. This is size M, I have worn this style at crowded beaches, a modest look and it stays on in rough surf. Spandex size M is comfortable for all-day wear, I sometimes wear size S for a nice squeeze feeling. Amazon link https://www.amazon.com/dp/B08LBQQ1LT/?th=1

That is an old link, don't order the Chinese gaff from Amazon. The original quality USA-made gaff thong is now at https://lexybblair.com/
