secretly fat 

Wearing clothing (especially a loose shirt) such that the wearer's excess weight is effectively hidden, often resulting in ambiguity as to whether or not the wearer is overweight. Particularly pertinent in a bar or club when physically evaluating a person of interest.

He has an attractive face, but with that loose shirt, he might be secretly fat.
