Heels can have your feet teetering on soreness and longing for Dr. Scholl’s foot pads. And no matter how many Pilates classes you take, you’ll never stretch yourself into the lead dancer at the Met. So if it’s height you’re after, switch to flats and get vertical with the right stripes.

Horizontal stripes may create unwanted width on top, but their linear cousins can be viewed from a different angle. Vertical lines are the best way to keep the eye moving up and down instead of round and round. Look for tops whose vertical stripes have a bit more width to lengthen your torso. The more playful the silhouette, the better (especially in softer fabrics), striking a fine balance between artistic and feminine.

Mac & Jac’s Colorblock Silk Georgette Shell echoes the chic mod fashions of the 1960s with a trapeze silhouette and ladylike rolled collar. Elevate your look with a fitted jacket and a fluid pant for a whimsical take on suiting—and a stylish way for an E to show her stripes.
