Red Nike Dri-Fit shirt, size M

I lost my red Nike Dri-Fit shirt, size M, yesterday around 3pm after I left the gym on Lark Street in Albany. It's a lightweight red tee with a white Nike swoosh on the left chest and black mesh panels along the sides. There's a small blue coffee stain near the hem and a tiny fray at the bottom edge—easy to spot once you see it. It was a gift from my sister, so it means a lot to me and I really need it back.
