Fitted to Echo flat chest + large bottoms. There's no skin element so I think this should technically work without TBSE, though I'd just recommend having it anyway (I haven't tested it without). Very small seam around the wrists and clipping is bound to happen in extreme poses/with very heavy C+ scaling/with certain items. I'd probably recommend tight-fitting pants; the model is currently in the pants from Key's Little Dark Age: https://payhip.com/b/ZhCDs
As always, please let me know if there are any issues, but otherwise I hope that you enjoy!
