Lululemon Kaleidoscope Tank Top Size XS

Lululemon workout tank with the cross hatch back. There's no tags attached and no size listed but based on my own size in Lululemon I'd place this at an XS to a petite if they carry petite.. I'm not sure. INo signs of wear outside of the tags removed. Very stylish and sleek/great for a run. All white interior. I wish there was more information I could share but there are no tags attached! The only way I knew this was Lulu was based off the emblem in the upper back between the straps, see photos.
