Here's one idea that I've been playing with. It would work best for a week-long trip - I'm not a fan of doing laundry when I'm on vacation - but could be stretched longer if needed. You start with the basics...
Tops: plain white tee, black tank top, chambray shirt, striped long-sleeve tee
Bottoms: black maxi skirt, jeans, khaki shorts
Accessories: black flats, sandals, cross-body bag, belt, hat
Then you add a bit of excitement...
The pop of color: solid-colored scarf, short print skirt, sneakers
Depending on your choice of prints, shapes, and color, your basics take on completely different looks suitable for different trips.
What do you think - would you consider packing like this? What's your favorite method of packing?
