congrats ! ur suddenly turned into your fursona/dollsona/idealized form/whatever.
what's the worst part? what's the really annoying part you're like "well obv this is the greatest thing but i wish i had realized how annoying X would be"
(this is assuming no one is weird about you suddenly being a dog or whatever; purely "what's the worst Practical part of your impossible idealized form?)
Aside from the whole “How do we wear clothes with our tail?” question (the likely answer is that we just start wearing skirts all the time), we’d probably feel self-conscious about our fox snout for a long while until we got used to it.
Answered this question rather simply; all Daemon outfits have tail slits! An effective solution to tail accommodation.
