Size 8 lululemon yoga tank purple

Bra is built in, no snags or stains, this is from about 2012/2013. I wore this to Bikram during that time. Super comfy! (I’ve gained 20 lbs and it still fits) I’m not sure if it’s a size 8 or a 10 but it fits both. I think it’s an 8. Lululemon brand. Racerback straps.
