I am on the hunt for some really basic but nice looking layers to wear under sweaters and jackets. I like to have different neckline options and a longer length. The first one below is a really nice crew neck and the second one has a higher neckline in the back which I really like for layering. The third option is a true tank with a scoop neck in the front and back. I wear mainly white but they come in so many good colors you can find the best neutral for your skin color and it is always good to have a few options in black.
