Clothing for worldbox at27 body?

[faker]

So I recently got this body with intent to use it for a custom figure, thing is, the cloths I had gotten for the old body don't fit much at all. Specifically the pants are way too small, and I've got no idea where I could find a basic t shirt and jeans combo to fit this monster body. The upper body isn't too outlandish, bbut the legs are insanely thick, like thicker than a normal body with thigh expanders.

Any tips on how to grab a decent pair that'd work?
