Also depends on whether the suit has hard boots that require a larger opening in the leg, or soft boots where a closer fit is possible.
FWIW, My Bare bi-lam's were loose fitting on my legs, and I had "issues", never wore gaiters, but did end up a time or two with my legs fully inflated looking like an idiot, and the rest of the suit in a slight squeeze. Now I have an off the shelf neoprene suit and I have no issues at all, it swims like a wet suit.
Never had a custom made dry-suit, so I don't know what I'm missing.
