This service was recently brought to my attention. The Anachronistic Gentleman Rental Service is a free "escort" service where all the men dress and act as if it's a different era. From the pictures, it seems like there's a range stretching from Victorian Britain to 1950s USA. As the founder, Miss Genevieve, a Columbia undergrad, explained:

"People need a license to be romantic and silly and extravagant, and walk on the backs of benches instead of sitting on them," adding that her mission is to "promote the elegant styles of the past."

It seems like a good idea, but it's clear to me that these men don't have a clear understanding of one important difference: Dressing differently or anachronistically is not the same thing as dressing well. If you look at the photos, many of the men don't have a clear sense of style. The proportions are wrong, the pieces of clothing and colours don't harmonize, some don't even fit properly. The just end up looking like they're wearing costumes, not daily attire. Some just look messy. Others have mixed metaphors: their clothing comes from different eras. So it's very admirable and a great effort, but they really need to study and understand their periods if they want to dress appropriately.
