It stretches quite a bit but the large is not big enough to cover everything it needs to cover. Fits a size 6 just fine for reference I am a size 12. Even if I had sized up it would still not fittighter sleeves than expected but super cuteVery tightI hate when I’m buying clothes and I don’t see any photo reviews so I wanted to contribute to the next potential buyers of these shirts!It’s a bit smaller than I expected it to be, I got a small but I wanted it to look a little bit baggy like the model in the picture. It still looks good for the outfit I have in mind. The material is stretchy, I’ve tried it on twice and it’s still in one piece but if you want it to look like the model I would recommend you size up!just as expectedThis shall is sooo cute!! its a bit smaller than i thought, as i'm normally a medium in tops and the large fit like a medium, but its still very cute and the material is as it looks. if you're thinking about getting it, size up and buy it! super cute!
