Try this on for size.

Neiman Marcus is trying out a "memory mirror" that allows shoppers to stand in front of it and "see outfits from 360 degrees and compare clothing options side-by-side," according to a story from CBS News. The mirror, which is controlled through hand gestures, also takes short videos that can be sent to friends via email.

MemoMi, the company behind the smart mirrors, created the devices in partnership with the high-end department store. According to the CBS News story, the mirrors were created in a top-secret lab in Dallas, where Neiman Marcus and MemoMi continue to experiment "with the future of retail."

Mimi Sterling, a spokeswoman for Neiman Marcus, told CBS MoneyWatch that "customers have had a very positive response" to the mirrors and that the devices are "helping to imporve engagement with consumers."

According to CBS MoneyWatch, the MemoMi mirrors only gather anonymous information regarding age and gender of customers. Everything else — videos, stills and the outfits customers have tried on — is password-protected.
