I'm so glad we got a Large, because this shirt fits more like a Medium.which actually worked out for my husband. I LOVE this shirt for its cuteness, its color, and its extreme softness.The "shady glade" color has a lot more green in it---making it more of a bluish-green (than the turquoise I see on my monitor). It's different--a good different.One can't not smile seeing a penguin on the front of a t-shirt. I'm so happy my husband has it, wears it, and likes it (he's super picky about fit and fabric).and this one is perfection for both of us!
