Lululemon Gray workout tshirt with pink accents

Lululemon gray stretchy and breathable tshirt with pink accents. No tags but the sticker says size 12. I wore it as a looser gym tshirt, I usually wear size US 6 for lululemon, so the size range for this tshirt would be between S (looser fit) and L (for tighter fit). Please see ptp measurements in photos. Fabric is soft, no visible sights of wear.
