Should he be jealous of her “work friend” who dresses well…?

“Ahoy Brian, Ali and Justin am I being insecure or does my girl belong to the streets? We were clothes shopping and she kept saying “I want to dress you like this guy at work”. We’ve only been dating for a few weeks so I’m not comfortable fighting back yet but that rubbed me wrong. Is this something I should be worried about and bring up to her or am I just being a bitch? I love the show and love you guys.”
