Sisters - names

My oldest is Vivian Tate- I liked the play on classic with a touch of masculine with the middle name.

Trying to come up with a second girl name has been a challenge- I swear I know someone with a name I like or I just straight up hate a name.

The latest name that I like, but don’t know if it “goes” with Vivian is Collier. We nn to Vivi & I was thinking maybe Coco for Collier so that her older sister can say the name 🤣 so do they “go?”
