Fit check

Look, I know I’m fat. I’m not going to look good in tights, but just want to know if these fit properly or anything else I can improve? The marshmallow picture shows my bib underneath, but I think maybe with a base layer I can cover it?
Hopefully, with time, the fatness will reduce over time.

Also, these are cheap Amazon clothes since I’m a beginner and don’t want to drop a lot rn.

Thanks yall
