When a Limited Time Challenge finishes the Voting phase, you will receive a message in your in-game Inbox with the results of your look.

The message will display your 'Voting Results', as well as your 'Unworn Items' and 'Seasonal Items' bonus scores, which will combine to show you your 'Look Rating'.
 
   

If you have scored a 'Look Rating' of 4.00 or higher, the results will display any prizes you have won.
Note: If you did not score above 4.00 or higher, no prizes will be displayed.

You can also view the scores for your Fashion House, Friends and view Top Looks for all looks entered in the challenge by tapping the appropriate tab.

When you receive your results for a Limited Time Challenge, prizes will be awarded when you view the challenge results.

If you did not win any prizes, you will be offered a one time opportunity to purchase the 4.0 prize the first time you view (and then close) your results.
