Homemade M&M costumes with with white gloves. Fits 7-9 year olds. My kids wore these together when they were in Grades 2 and 4. There's velcro on the sides to keep in closed around their sides, but didn't work very well for my younger one, which is fine - just might see the foam a bit. $40 for the set. Pick-up is in Kitsilano near Blenheim/W 10th
I also bought white hoodies and white sweatpants (couldn't find sweats for my Grade 4 kid though) for them to wear underneath - bought a bit bigger so they could layer under the hoodies.
White zip up hoodie size L (10) - $15
White pullover hoodie size medium - $15
White sweatpants size small (6-7 years) - $15
