Why will it save you time and energy? Because you will learn to re-use the key basics and therefore cut down on washing. You also won't be that person rummaging around in the dark dorm room at 5:00am before a flight searching for something somewhat fashionable. You'll instantly know what goes together because you planned it that way (Hot tip here: check the destination weather forecast BEFORE you leave)
Inspired by my 2014 trips to Vietnam, Cambodia and Thailand and all across the USA; here is one basic I wore again and again (and again and again) and didn't get sick of!
The Basic: Grey T-Shirt, BondsFirstly, I want to say that I swear by Bonds T-Shirts. I have never found a better, more comfortable or flattering tee. They keep their shape after hundreds of washes, have a great cut and are the softest cotton.
