Yeah, that is an issue. Also, it must be harder to breath in that unless magic can create constant-force stretch matterial that requires no more force applied to stretch the first tenth-of-a-hoof-length thatn the fifth tenth-of-a-hoof-length. A properly fitted suit would only be the same percentage smaller than the wearer in every area as one fitted for Zipp. Well, maybe a LITTLE variation due to materials-science differences between muscle and fat, but either way, not only Rarity, but Twilight (who knows materials science), and Dash (who knows stream-lining suits) are looking down from Skyros and shaking their heads. Well, unless, as I said, magical properties that violate the spring equation.
Simple version:
Force Needed = (A Constant Value Specific to the Specific Spring) × (Distance Stretched From Unstretched Length).
