For summer office attire, I love a simple, peep toe slingback. It's more professional than a sandal, and it looks great with pants, skirts, dresses or Capri pants. I'm also obsessed with finding yellow shoes, so these really are perfect.
The Sechelles Wait Your Turn Leather Slingback from DSW has classic looks that won't go out of style. For only $59.95, these leather slingbacks make a good summer investment that will work well for spring and fall too. In case you aren't loving the yellow, these shoes also come in black, pewter and red.
