You may have been there before. I hate it when I order something online, thinking that it would fit me perfectly only to realize on the day it arrives that I should have ordered a size larger. This happened to me recently. I received a cool jacket in size medium yesterday, but it feels somewhat too tight when I pull up the sleeves. I personally think it looks better with the sleeves pulled up. I know I can return it, but I don't feel like it. It's too much of a hassle to return things. I feel tempted to purchase one in size large.
It's really a cringeworthy situation.
