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.

Travel uniform

Picture this: You're going on vacation to Italy. You want to relax and feel chic and timeless, a la Grace Kelly. These mix-and-match pieces would do the trick...(Of course, I'd also love to wear them in New York, too!)

1. Maxi dress. The perfect sexy dress for relaxing at the beach, then heading to dinner.
2. Eyelet dress. Fresh and sweet.
3. Cashmere cardigan. Because red looks amazing in photos.
4. Denim jacket. Nothing looks cuter than a sunkissed girl in a denim jacket.
5. Gold bangles.
6. Oversized straw tote.
7. Red bikini. (A cheaper one here.)
8. Sandals. I've spent months searching for summer sandals that are pretty and comfy. These, finally, are both. (And only $36!)
9. Negroni. A rich and bitter cocktail, best served in a little Italian fishing village.

What do you always pack for vacation? I'd love to hear any tips!

P.S. My friend Susan's genius honeymoon tip.
