Even during the 2008 downturn, "the underwear area was very strong," Eric Beder, retail analyst at Brean Murray Carret, told CNBC Thursday.

"People still wanted to spend money. So they could spend money on underwear if they were feeling good about themselves, even though for most people they wouldn’t show that off."

Michaell Yoshikami, YCMNET Advisors CEO, said many put off purchases for as long as possible and now want to replenish the underwear drawer.

"I think there is a cyclical recovery that you’re going to see and it does suggest that the economy is recovering (and) consumers are spending more money," he said.
