I am looking for a manga where in the final chapters (I think) the heroine decides to become a stylist for models. I do not think the entire series is about modeling and fashion but I could be wrong. The only part I can strongly remember is she is styling a model on a bus or trailer and she is talking to her love interest. I think the heroine wanted to be a model but realized she could not be one and settled for styling. Please help!

I'm pretty sure you're thinking of "Lovely Complex"
