This is a knit from Crepuscule. While it's relatively breathable for this brand's knits, it's also thick and tightly woven. As the seasons change to fall and winter, outfits tend to become darker, but just wearing this underneath can brighten up the whole look. I think it's a worthwhile item to have, as you can wear it in the spring as well, making it suitable for almost all seasons. I'm selling it this time because I'm short on money.
