that is a very interesting point!f/a who can fit into her jumpseat with the lapbelt/harness provided (w/out use of an extension.) and yet the red dress still doesn't come in her size. Then...yes, they will either have to offer it in larger sizes or do away with it I suppose.
what is the maximum uniform size the jumpseat will accommodate based on the length of the seatbelt?
an excellent question that I do not have an answer or even know!
