Lululemon Athletica Cool Racerback Tank - Jaded

Lululemon Athletica Cool Racerback Tank. Believe this is the Jaded colorway Approximately Size 10. Pit to Pit is 15.5”, waist hem is 20”. My fiancé generally wears these as a size 8, and she feels this is a bit bigger than she usually likes, so basing the size 10 off of that, but size guides put this like right in the middle, so 8 or 10 would likely work. Please let me know if you have any other questions!
