This is sooooo cute!! I'm 12 years old and 4' 7" and it fits perfectly!! I got a xs/s. As you can see, the material is knitted and is really soft! It was thinner than I expected, but is still really warm! The only reason I gave it 4 stars is because it FOREVER to get here! It took about 5 weeks! Other than that, I highly recommend this sweater!!
