Lululemon Radiant Long Sleeve Heathered Tee Shirt Top There is no size. I believe it to be a 8 or 10 but please refer to measurements to be sure of a fit. Leave this lightweight layer open to cool down quickly after a sweaty class or button it up to bask in your post-Savasana glow. Made from a blend of Pima Cotton for the ultimate in softness and stretch four-way stretch oh-so-soft handfeel Originally there was a loop for a button on the side. The lop has been cut off. Otherwise, top is in good condition! Approx. Measurements: Length: 24.25" down from back base of neck Across underarms: 17.25" Shoulder seam to end of sleeve: 27.25" C6
