Help Please (Read Desc.)

Ok. So basically, I want to host a raffle to celebrate 400 followers, but I need to confirm how a raffle works. Please read the next paragraph fully (I know it's long).

So for a raffle, I would make two outfits on sides of the skin and you would vote which one you liked better. Then I put all the people who picked the first one in a draw and all the people who picked the second one in a draw. I pick names and so then there's a winner for each outfit. Now this is where I get confused. Does the winner get a prize or something... I'm not sure. Please tell me in the comments! Also if something I said about how raffle's work isn't right, please correct me in the comments. Thank you!
