Caitlyn & Kylie Jenner -- Orange is the New Dad!

Caitlyn Jenner and daughter Kylie grabbed lunch Monday ... the first time they've been seen in public since Kylie's 18th birthday party. 

The two nibbled on sushi at Sugarfish in Calabasas after attending a NOH8 event in LA. 

They were matching right down to the lipstick. Caitlyn opted for a more neutral color, while Kylie wore blue to show her support in honor of world bullying day.
