Markey's Chef Pants Striped Two-tone Set Both are size 100, but the two-tone ones are slightly larger. They look cute worn oversized with the cuffs rolled up. They can be worn for a long time. We had our child wearing them when they were around size 80, and they were baggy. The fabric is thick and sturdy, but it's a stretch material. We used them for going out, so there are no noticeable stains. The washing has given them a nice faded look and a good feel. Markey's
