I scored three shirts at Goodwill a couple weeks ago! This one had to be brand new and is really comfortable (obviously, since you've seen it like three times already) with the exception of the sleeves. They were a weird three quarter length with little elastic cuffs. You can see them here...
So I chopped them off,
turned them up twice and sewed.
If you don't have a sewing machine or do but don't know how to operate it (hey, I'm not judging), you could always do a simple slip stitch hem on the sleeves. Turn them up twice like I did and then sew em down with a needle and thread. Very easy!
And just to make this post a little more interesting, here are a couple festive summer outfits. I know, I know. I see that hem.
