The effect of making a t-shirt seem more purchasable by putting it on a young attractive woman with breasts that are to big for the t-shirt.
The t-shirt tends to be worn by women, but can sometimes be worn by muscular men wearing a t-shirt to small to make him look stronger.
As a man this effect makes us think we could look like the man wearing the t-shirt or maybe that the woman wearing the t-shirt or that of similar attractiveness will find us funny or attractive.
Unfortunately the reality is these corny t-shirts that look good on the models will not make you look bulky or get you pretty woman.

Jack- Ahh you idiot you got totally taken in by the T-shirt Effect
