This is a fun, cozy sweater. i feel you can dress it up and use it casual too. i bought the ivory in size s, i'm 5'2''. although i put it runs true to size, it's is a tad tight around my upper arms, not uncomfortable. i have normal to somewhat skinny arms, so i don't think it was my body type. i didn't check other sweaters in the same size to see if it was an isolated case. it is to be worn loose, it has quite a bit of material all around mid to lower part, just fyi.
