This is the ultimate SI Swimsuit giveaway you don't want to miss!

Kelsey Hendrix | Dec 3, 2015

It looks like Santa Claus is coming a little early this year, and he's bringing with him the ultimate SI Swimsuit giveaway! For the first-time ever, we're giving away not one, not two, but 10 signed, limited edition copies of the 2014 SI Swimsuit issue.

So how do you win? It's simple! Follow us on Snapchat (siswim or scan the code picture below) and watch our story to find a secret question we need your help answering. Then tweet at @SI_Swimsuit with the answer. We'll give an issue away to the 10th, 50th, 75th, 100th, 150th, 200th, 300th, 400th, 500th and 750th person.

Keep in mind that a Snapchat story only lasts for 24 hours, so you'll need to find the question and send in your response before 11:59pm EST tomorrow to be eligible to win. Winners will be notified via DM when the contest is complete.

GOOD LUCK!

See some of Nina, Lily & Chrissy's best moments!
