Wear them with slim pants or tuck them into a skirt; either way, an interesting neckline means you don't need much jewelry, just a simple pair of studs.
Comfortable enough for three hours of standing, yet they still look sleek in a cool '90s minimalism sort of way.
Maybe you're just not a dress girl. Or maybe you are, but you want to stand out in the sea of sundresses. Either way, bright, well-tailored pants are your answer.
Tweed is sort of the unofficial fabric of luncheons and showers. In neon, it's young and fun, not staid.
Find one that's got a little bit of flounce but not too much, and you'll look girly but not caricature-y.
Toss them over dresses to shield yourself from intense A/C, or wear them to pull together separates. White's particularly good, because it's crisp but not corporate like black or navy blazers can be.
They're the default for a reason. Invest in one as an easy starting point, but just keep the rest of the look simple, not too Betty Draper-ish.
