What to Pack For a Vacation in Cancún, From Swimwear to a High-Tech Fanny Pack

Topshop V-Neck Empire Waist Maxi Dress ($75)

While staying at the resort, I learned that just because you remain on the property the whole week doesn't mean you don't dress up. I was impressed to see people in formalwear for dinner and sunset drinks. And I was equally relieved to have brought a nearly floor-length dress to match the ambience. We enjoyed a fancy hibachi dinner and my green evening dress fit in perfectly.
