I ordered this blue plaid shirt in my usual size medium. I'm 5'2" 150lbs 36D for reference. I wouldn't classify this as really oversized, maybe just slightly. I was really happy with the feminine blue colors and how soft and lightweight this shirt is. It also has a nice drape to it. I don't think I saw (maybe it's not pictured) but the sides do come up kind of high, not an issue for me because all my pants and jeans are high waisted but could be an issue for others. Looks good with a few buttons done up or unbuttoned with a tank under.
