My new summer uniform

We were packing for Chicago this morning, and I was thinking about summer uniforms. What's yours this summer? I keep spotting beautiful women around town wearing white jeans with grey T-shirts. Fresh, clean, classic. Perfect for day or night. Here's how to get the look...
Grey tee: Get this one. People usually think of tees as basics that you can find anywhere—Gap, Old Navy—but not all T-shirts are created equal. Certain tees can be wildly unflattering. You want to stay away from fluttery sleeves (like this), high necks (like this) and any thick fabrics. Instead, find a thin tee with a lower crew neck or V-neck, which are soooooo much prettier.

White jeans: My favorite pair, hands down. The cut is fantastic. I bought these before a trip to Paris three years ago and have loved wearing them ever since.
