Also, don't rely on what you think the weather will be like when you arrive--check the weather channel before you pack. For example, July in Los Angeles is usually quite steamy but the weather outside is actually cool.
Think Uniform Stick to simple color palettes (try white, black and gray). Not only does it look chic and classic, you won't have to fret every day over what outfit to wear. If Sheena from The Uniform Project can make one outfit last for an entire year, surely you can make do on a few outfits and change it up by accessorizing.
We like to wear our bulkiest items on the plane just in case there's going to be some cooler weather at our destination. Boots, hoodies and scarves can be worn at the gate which saves room in your suitcase for other necessities.
It's usually a safe bet that the hotel will have shampoo, conditioner and soap in stock. But it's best to check and see if your room comes with a hair dryer (which will save you from having to tote one in your bag).
When we're packing up to return home, take advantage of the hotel room's plastic laundry bag for separating your dirty clothes from the clean ones.
And we always like to make sure we separate our bag from the rest by tying a gold ribbon around the handle. Making your bag stand out from a sea of black suitcases will save time (and sanity) while waiting at baggage claim.
