I've had this Tommy Hilfiger cotton button-down shirt for years. I wanted to wear it differently, so I wore it unbuttoned with a tee inside!
StylingFun tips for this outfit:
1. Wear a button-down shirt UNBUTTONED
2. Match a tee of similar shade inside to stay coordinated (i.e. pink and pink)
3. Pair something in contrasting color on the bottom (i.e. dark blue skirt)
