I thought that once you used a salon pass to change your appearance that you had 60 minutes to go back in and adjust things? This is not the case, and it's impossible to get a feel for how your character moves around after adjusting your height without exiting into the shopping plaza to run around a bit.
This isn't the new character grace period, I'm pretty sure I remember seeing it tell me you had 60 minutes to continue fine tuning your changes before you'd have to spend another pass to change anything again.
If I'd know there was no grace period at all, I would have rolled a new character and used their 5 hour grace period to tweak and save appearance data options and then deleted them.
So, I'm asking if this is the intended behavior, or if this is a bug, for future reference so I can avoid wasting in-game items. And also so I know to only use 2 character slots so I can change appearances without time pressure.
