This is NOT a tip on how to win.  This is a tip on what happens afterward.

My suggestion is that if you enter either fashion show, keep track of your diva bucks daily: on a piece of paper or somewhere on your computer.  Make a note if you buy something, and include the date and when you earn your diva bucks.  Do this for each day.  It seems that with the last few Fashion Shows, winners have not received their "cash" (divabucks) they were supposed to receive.

I can't say if anything will be done about this since this issue is overlooked here and on the French Forum.
