Girls' Casey cardigan sweater

Bought it on sale so I thought my 3.5 yo daughter could fit a size xs (4/5yo). Why do you guys make your clothing run so small. The size s (6/7) for my 3.5 year old girl fits but really?? She’s just an average girl. If the company labeled this correctly I wouldn’t have to be stuck with a small cardigan that I can’t return bc it was on sale.

I purchased a XL sized cardigan for my 12 year old girl. The color is a pretty blue. It runs a little large on my daughter but it will fit her soon as she is growing so quickly. The fabric is thick enough for fall and winter. She is very happy with the new sweater!
