Louis Garneau Cycling Top Size medium (slim fit).
New with tags. 
"Lite Skin" model 1025125
Dimensions laid flat, unstretched: 15 inches across (30 inches chest circumference), with a decent 5-6 inches stretched flat. It fits like a small. 22 inches from back of neck to hem. 

Features: double back pockets, one with a inside cord hole for your devices. 
Pretty decorative swirls on front and back (subtle- blend in with a similar color). I have the contrast turned up in some photos to actually see them, as they are almost clear. I'm not sure if they are reflective or simply the Garneau Logo lettering. 
No inner shelf bra or lining fabric- just one layer tank top. Great for everyday wear, jogging, yoga, working out. Doesn't look like cycling gear. Note: the fabric is opaque NOT sheer. I held it up to the sunlight and then adjusted the contrast on certain photos only to show the decorative design details.
Color: bright pink- like electric barbie pinkish-orange. If traffic cones came in pink, they would be this color. The photos taken in doors most closely resemble the actual color. Cars will definitely see you in this ;-).
Fabric: The fabric is wonderful. Silky, lightweight, and feels great next to your skin. 92% polyester, 8% spandex. It's not as thick as regular cycling jersey fabric: light and breathable with a nice amount of stretch when you're hot and perspiring. Perfect for hot summer days. Plus it's made with sun protection! Note: the fabric is NOT see through.
