I have a sweater like this (sweater without the hood version) and it is so warm and perfect for layering over thin tanks or tees. It could be worn alone, but it would be so sexy like that ;) They are just thick enough, and they do not make you look fat, like some bulky knits tend to do.

DETAILS:
Combine sumptuous texture with a comfortably chic, body-conscious fit. Imported acrylic/nylon/wool/Lycra® spandex.
Sizes XS-XL. #217-292
