Vintage Toronto girls School gym uniform XS Unique Jersey

Vintage Toronto girls School sports uniform. It's like a form fitting jersey type piece. Zip up on back, sleeveless. XS. Monogram LCS on front, and number 11 on front and back. I'm not sure exact age, but it looks 1950s to me. due to its age there is general wear around edges. there are some small discolored spots, which you can see in the photo with the LCS monogram. to the right of the 11. really unique piece of Toronto history.
