I love my new off-white "sweater," which is more of a t-shirt than a sweater to me. Anyway, a rose by any other name. The t-shirt is very light-weight and very breathable despite being made mostly of acrylic textile. I wear a muscle shirt underneath the tee just to have a little more coverage and because I like the look / outline of a muscle shirt underneath It's the perfect weight for summer, but can also hold its own against a cool breeze, especially with a tee under the tee. I'd love to have one in every colour. I haven't laundered it yet; most likely I'll dry clean.
