female lead’s wardrobe was terrible!

I loved everything about this storyline but I absolutely hated that wardrobe design made the female main character dress like a 15 year old high school kid throughout the whole movie, made the love connection unbelievable. I wish they would have dressed her more mature, more feminine. Ceo in suits and always handsome falling for a part timer in baggy pants and XL sweatshirt did not convince me of their affection for one another.
Unfortunately, my rating went down significantly because of it.
