Answer: White House | Black Market! It actually used to be 2 different stores - White House first opened in 1985 and Black Market (owned by the same company) came in 1995. They joined together in 1997. As of 2003, the store is owned by the folks at Chico's. As of 2011, it is the place where I got the only semi-fancy party clothes that will fit me in December.
Wikipedia was first launched in 2001.
The More You Know: My mom invariably calls White House | Black Market "the Black and White Store." There's about a 30% chance that if pressed, she couldn't give the correct real name.
Also, that font is called Hoefler Text.
