A large, baggy shirt with unusual excess armpit fabric. Wombats are great in the winter and sweaty in the summer. (But we wear them in the summer anyways) A good wombat is always belted with a thick, matching, but not to flashy belt.
If you buy an overly HUGE shirt and belt it to make it look good, then u have a wombat shirt, congrats!

When you can tell when a woman is wearing a bra or not, there is the definite underlining of the boob which the shirt may catch under.
