Great spring/summer staple
I have a couple of these tanks (in beautiful bright colors!) and love the dress equally as much. I have the tanks in size S and decided to size up to a M for the dress and it's perfect. Fitted but flattering!

Hi KB,
We're so happy to hear you are loving the West Organic Rib Tank Dress. It is truly a year round staple piece. xx
So thrilled!
Wanted another West dress since buying it in bright pink in 2019. When I saw this 💙, I was determined to stick to my budget! When the price dropped the first time, I still had willpower. When it dropped the second time it was a sign to me from the universe! Get it!!! LOL!
I'm taking it to Maui in a few weeks. These dresses are perfect to dress up or down! Out to dinner or a beach cover-up, and soft as your favorite nightie... it just feels yummy!
