Hi Gabriela,
We are sorry you didn't like the fit of the bottoms. We do our best to show our products on as many body types as possible. One of our models that wore this set is curvy and fuller than our size S model. She's wearing a size M and it didn't fit her as a thong, but everyone is shaped differently. The most we can do is show as many photos as we possibly can.
This isn't a conservative or covering suit by any means. The cut is very high waisted and narrow and on the back it is cheeky for most. But, we know that it all depends on each client's figure, and there's no way to guarantee that it will fit everyone exactly the same.
Thank you,
