Nice ribbed shirt. Heavier then a t-shirt for cooler weather.
This is a nice shirt. It is ribbed and provides some warmth for cooler days. The material is nice and the sizing is as expected. It has good stretch and the color is as shown.

Great quality and very cute!
I can see this top becoming a real staple in my wardrobe, as I love a simple black tee and this is an upgraded version of that. The material is thick enough to not be see through, but light enough to be comfortable even in hot weather. While it is very tight fitting, I like that the neckline is high and the sleeves are a bit longer lending it a very classy, polished look. I typically always wear a small in tops, but based on other reviews, I went with a medium and I’m glad I did. It fits perfectly and I think a small would have been too snug. If you are in any way self conscious about your shape, there really isn’t any hiding in this top so bear that in mind; it is very form fitting. I recommend this top and I will likely order another color because it just feels like a good top to have on hand for a quick, put together look.
