She hit the nail on the head with this look from Fashion Under $100 for transitioning into spring. Even though the look is for a reader who wants to wear jeans to her bridal shower, this is a great look for early spring! Skinny jeans can come off looking to casual/rocker but the tunic style top with the bow detail pumps it up to lady like feminine. Adding the flats doesn't call to much attention to the jeans, so this lets the girlie top and accessories do all the talking.
Now off to find a pair of black flats in a size 9.
