Im getting ready to pack for NYC this evening, which will be a challenge for sure. There are just so many things that I want to bring! I can already see a ton of stuffed suitcases in my near future.
If you are packing for vacation too, a while back I posted about "packing light". You can find that post here. It has a guide to staples you can pack that can be layered, are versatile and can be mixed and matched. The clothing featured in "packing light" included winter clothing, boots, and colors, such as navy, black and camel. Here is another guide for suitcase staples that include a pop of color, more appropriate for Spring!
Good luck and Happy Travels! I can't wait for NYC!
