Traveling for the various fashion weeks is a large undertaking, especially if you don't live in close proximity to where the event is taking place. Luckily, Mr. Porter reached out to some of the world's most stylish and influential people to get their tidbits on the must-have essential as they hit up the cicruit of New York, Milan, and Paris.

The film features substantial cameos from the likes of Samuel L. Jackson, Thom Browne, Scott Schuman, Tommy TonBrian Trunzo and Matt Breen from Carson Street Clothiers, and more. Then, the discussion of underwear came up, and this knowledge was dropped: "Thongs are good, because you don't see the seam in the back [of the pants]," by a dude, bro.

That's right, some of the most street-styled guys are wearing thongs so you when see their butt, it's all trouser. Still, if that's not your thing, you can watch the rest of the video and plot your way to the next fashion gathering and unveiling of runway collections.
