If you're into getting around the world and seeing things, you probably don't only want your wardrobe to be stylish for the pictures you'll be taking. There are many other aspects like comfort and convertibility for both combining differently and dressing appropriately for any kind of occasion. That's one of the many amazing reasons to thrift shop. You don't buy stuff categorised as "basic" or "business" or "casual". You buy what you like and wear it how you want. It's your call.
