I see a lot of jackets that have the hem of the jacket and the sleeve about even these days...traditionally the hem of the jacket was always a couple of inches longer than the sleeve...still a tough call because it depends on how the jacket is cut and how snuggly it fits. Months back, Cessna Towser posted a photo of a kilt shop window that had a kilt outfit in it where the jacket was longer than a regular kilt jacket and that outfit looked great so I guess it could be done.
