Lululemon Cool Racerback II Lined Up Athletic Tank, Size 4

Lululemon Cool Racerback II Lined Up Athletic Tank, Size 4 Super soft athletic tank top made of sweat-wicking, four-way stretch Luon® fabric. Designed with yoga in mind but great for all workouts and activities. Color is "Wee Are From Space Black Slate" with black trim. Excellent used condition. No flaws to note. Missing tag. The bust measures 13.5" on one side while the garment is laying flat - I believe that it's either a size 4 or 6. The fabric is very stretchy and forgiving so I would think it'd work pretty well either way. If you're unsure, play it safe and assume it's a size 4. Machine wash and dry.
