With my DD it wasn't about comfort, she'd wear the fanciest floofiest princess gown she could get her hands on. What I found to be important was the ease at which she could use the bathroom. When she wore her Elsa dress to the MK in order to get her comfortable enough to use the bathroom I had to take the dress off, every time, and with those thin netted sleeves it was a chore to carefully remove and put the dress back on. She was 3 at the time, next time I'm definitely going with a lower maintenance dress.
