The results are in — you're probably not getting jeans for Christmas. But you've got a good chance at slippers.

For online retailers, November and December are unlike any other time of the year — both in the number of people shopping and what they are shopping for.

Slippers outsell heels by 25% over the holidays, according to data from online retailer's reward program. For comparison, during the rest of the year, heels outsell slippers by 350%. Unless you're in Florida, where heel sales around the holidays nearly double that of slippers.

Want to buy pajamas? The masses say ditch the set — go for the pants. Customers buy twice as many pajama bottoms as they do pajama tops during November and December.

Maybe it's because all that holiday food has people yearning for stretchy pants. Men and women buy fewer pairs of jeans during the holidays – men's sales go down 11% and women's sales down 10%, Zappos found.

According to Deloitte’s annual holiday survey, more consumers than ever are planning to shop online for gifts this holiday season. Online retailers are working to rope consumers in with customized rewards programs. Zappos gives frequent flier-style rewards for social engagement and log-ins. Target offers discounts for signing up with its Cartwheel app. For customers who pay for Amazon's loyalty program, Amazon Prime, there's early access to certain deals.

So, once they find a deal — what are people buying?

Men buy 95% more baby onesies during the holidays. Socks sales are flat, but lunch bags are up double digits.

When it comes to jewelry, bracelets see the most holiday pickup. During the holidays, men buy 76% more bracelets, 59% more rings, 44% more earrings and 42% more necklaces. In the same time, women buy 59% more bracelets, 42% more necklaces, 24% more rings and 14% more earrings.

What aren't women buying? Handbags. Handbag sales by women on Zappos go down 5% over the holidays while men by 23% more of them.

Wherever you're shopping this holiday season, don't forget to keep an eye on your rewards programs. The 2015 Colloquy Loyalty Census found that the average U.S. household is enrolled in 29 loyalty programs, but actively participates in only 12. Are you missing a deal?
