I could use some help here team

First day of school tomorrow.
It's my senior year.
I got my senior shirt, it's long sleeved.
So, the question is... do i chop the sleeves off now, or should i wait until spring?
Wheather i do or don't isn't a question anymore, it's when.
See, it's pretty hot right now, and will be for aother month or two, but then it's winter. I'll probably be wearing the shirt every two weeks or so and sleeveless shirts aren't exactly practical when it's cold out, but i could make it bareable. Then it warms up again, and bingo, sleeveless shirts ftw.

So NS, do i chop them right now, or should i wait until the spring.

Thanks.
