"Come on! We're supposed to dance!"
-- Parvati Patil at the beginning of the Yule Ball
Parvati Patil is a Gryffindor in Harry’s year. She is good friends with Lavender Brown.
Parvati has long dark hair which she wears in a plait. Harry by his fourth year thought her very pretty, while Dean Thomasconsidered her and her twin to be the best-looking girls in their year (GF23). Despite this, apparently neither girl had an escort to the Yule Ball of December 1994 until very late, when Parvati agreed to attend with Harry, who asked her after being turned down by Cho Chang (GF22). Harry was a rather disappointing escort, paying Parvati very little attention, and Parvati took up with a boy from Beauxbatons instead (GF23), and was somewhat cool toward Harry for quite some time afterward — understandable on the whole, since he had ignored her vexation. Parvati wore robes of shocking pink with gold bracelets and braided her hair in plaits with gold.
Parvati’s best friend is her fellow Gryffindor Lavender Brown. Both Parvati and Lavender are very impressed by Professor Trelawney and love Divination.
Parvati joined Dumbledore’s Army in October 1995, attending the first meeting at the Hog’s Head (OP16).
