Second-Hand Robes

From Absit Omen Lexicon

Second-Hand Robes is found at 36, South Side, Diagon Alley.

It was where Molly Weasley took Ginny Weasley to buy robes for her first year at Hogwarts. This may also have been the same store where she bought Ron's dress robes in his fourth year, for the Yule Ball.
