So, is it 500 credits per item, or outfit?
And does the set bonus stay with the sponsor you had originally or the one whose apparel you switch to? What about mixing benefits from different sponsors?
Or are you limited to changing styles from the same sponsor. I.e. moving from common item to epic or rare item?
Whatever your apparel is set for, you keep that boost, just change the clothing. If u have the se hat, for longer drives, you can wear something else, and keep the abilities, as they call it, of the se hat. You can change as many times as u wish. You can even go back and change to a hat that has different abilities, to say give u more coins, but keep wearing the hat u think looks better. The way I understand it, the 500 credits is a one time deal, to wear whatever, as much as u want.
