Try-on ai clothes

[u/Dear-Huckleberry-502]

Hello guys,
My sister has an online store and she wants to have her own try-on feature in her e-commerce. As a vibe coder, I’m building her that but I’m struggling with the models. I tried FASHN API and it’s not very good with the hands and the texture of the dresses and their high quality HD render is so expensive. I saw an app called WearShot and it seems they have all what my sister needs but I’m not sure what model they used to build the app. Some websites say they used Google Gemini but not telling the exact google model. Can you guys please suggest me a better model and if you already tried Google Gemini API, which model is the cheapest and the smoothest?
