Think it’s a 8 or 8, the folds at the straps are designed to show size- can’t recall but this may be a 6. The last photo shows it with a size 6 Dottie tribe tank on top. I normally wear an 8, this is snug on me like a normal 8 might be depending on the style.

Great condition without flaws.

Check out my other listings, as I am selling many of my old Lululemon items, including mostly tops in size 8, and bottom size 4.
