But before we get to to that, the fit kits are highly organized this year. Each of the 103 garments has a number. The garments on the left are men’s sizes in order of S, M, L, XL, etc. The garments on the right are the women’s sizes in order of S, M, L, XL, etc. The garments numbered from 51 to 77 are unisex. When you try something on, you must wear an undergarment and you must put the hangar back in numerical order. Why? To be courteous to your fellow members. There is a box at the bottom for gloves, head thingys, caps, and arm, knee and leg warmers. Please put these back in the same bag and then put them back in the box.

Items 1 to 50 are men’s cuts, 51-77 are unisex, and 78 to 103 are women’s cuts.
