Sleeves should fit/look like this...
NOT like this...
Since I've been working at Belk for the past 6 months, I'm starting to develop fashion do and dont's.
In the second pic, the t-shirt just looks floppy, unproportional and messy.
I avoid regular t-shirts at all cost now and only wear slim fit clothes. Not skinny jeans, but slim jeans ad shirts. etc.
