PETMHS Women Festival Rave Feather Harness Bralette Strappy Full Set Body Harness Burning Man

Does the front part of the bottoms fit like underwear? It almost looks like the thong part goes all the way thru the front. Uncomfortable?

Anyone know the length of the feathers approximately? I'm thinking of buying another color feather to add, but don't want them too long or short.

Does it fit well on plus size
