(Diane Kruger, Pippa Middleton, Rachel McAdams)

With all the September issues on the newsstands, everyone (including myself!) is getting excited for fall fashion. But it’s still summer until September 22. So focus on pieces in your closet that easily take you from season to season. A striped skirt is a proven classic. It’s just as popular now as it was when Rachel wore it at New York Fashion Week in 2009. And as Pippa shows, with tights, you can easily rock it in cooler weather. Here are some of my affordable faves:

1. Forever 21, $11.80
2. Free People, $68 $39.95
3. Ann Taylor, $78
4. BLQ. MKT, $48 $35

Stay tuned to see how I wear my striped skirt in this week’s Staples Series.
