The Kelly of the online shop

"The Hermes Kelly 25CM Togo is a touch more formal, a little more appropriate for an evening out, a business dinner, as a more refined look. The Birkin is more sporty, more casual. Often people use it as a briefcase, throw in a change of shoes," says Trina Sams-Manning, manager of the Hermes shop in Fairfax Square, which recently reopened after a major facelift. 
  Inga Guen, who sells gently used Kellys and Birkins at Inga's Once Is Not Enough, a high-end consignment shop in Northwest Washington, is even more emphatic about the difference. "A woman who is going to wear the Kelly is of very erect stature, she comes from money, very good background, is extraordinarily educated, and life to her is one where she will be very inconspicuous," says Guen, an avid Kelly carrier. She cuts a bit of slack for the Birkin femme, who "wears Manolo mules, a pair of jeans, a little Chanel jacket. She is the younger woman."
