Is it cold in here or is it just me?

Honestly, is this really necessary? Do mannequins have to have obviously erect nipples? Is it not enough to make the shapes of breasts to signify it is a lady or pecs to signify it is a man mannequin? Do mannequins need nipples at all? I know I would shy away from purchasing this shirt. Seems a little too thin to me. And I would not want to even risk the chance of being cold while wearing it.

I ran across this nippy mannequin in Academy while looking for a canopy to put up above my art booth next weekend. I ended up getting one that I absolutely love at Sports Authority (not because of this mannequin, but because they had what I was looking for at the right price).
