"Good taste shouldn't have to cost anything extra." - Mickey Drexler
Seriously, anything and everything. You can even add a cute seersucker blazer (or other blazer) and wear it to work with cute heels and a business-worthy blouse.
Espradilles will make it perfect for daytime weekend wear.
Flats for anytime wear.
Tanks, tees, shirts, whatever's clever. :)
