Starting the weekend off early, Joe Jonas and his girlfriend had a leisurely lunch at Cafe Gitane in New York City on Friday (September 13).

The middle JoBro went casual in a white v-neck T-shirt and black shorts, while ladyfriend Blanda Eggenschwiler donned a green jacket and black leggings as they chowed down.

Taking in some of New York Fashion Week with the former model, the 24-year-old musician talked about his gal's influence on his own style.

When asked about her input, Joe tells E! News, "She will always say what she'd like to see me in," though he admits he doesn't always listen, sharing, "Sometimes. Sometimes you've just got to go with your gut."
