Shirt Sleeves

[mutated_queer]

I got a really nice new shirt for job interviews. I'm finally broad enough that I can't wear kids' clothes but I'm still short, not a problem with length of the body since it gets tucked in but with my arms a bit more so. This shirt has a  a nice bit inside the sleeve which makes me think I can fold it up. It looks like this- left side folded up, right not obviously  and don't worry I plan to iron it before wearing



Is that acceptable or some sort of faux pas?

I'm not sure if this is the right place to ask but I can't think of anywhere else.
