These Madewell tanks are such a great deal right now. A handful of colors and styles are on sale for $12.99- marked down from $18.50.
I have at least 4 of these tanks and I wear them constantly because they are so soft and so light and easy.
I can see three striped options at $12.99 and a lilac or bronze color for solids. These are really popular tanks so they will sell out fast.
Shipping is free. I have pink, white, navy, pale blue and the white and navy stripe version. I will say I prefer my normal size (medium) the arm hole is a little loose so if you size up, you might find you need a camisole under the tank.
You can also shop Madewell directly by clicking here. It looks like just a few options are available at $12.99- otherwise there are a lot of colors priced at 2 for $25. The shipping is not free but it was super reasonable for me at $3.00.
