I was planning on wearing sweatpants on my flight from East Asia to East Europe, but my parents shut me down, saying that it's not looked upon kindly and people wearing sweatpants are usually a bit of a gangster people. This seems a bit weird for me, as I see sweatpants as just comfortable clothing and you wear your comfy clothing on flights.
And I looked up "Airport queue" to look at what people wear and for men, jeans does seem to be the prevalent option as my parents said, but women seem to mostly wear yoga pants, which I see as social equivalent of sweatpants. They also reminded me, that I'm not going to Europe for sightseeing, but studying, so my choice of clothing should be something that the border agent will not likely see as "gang" and hold me down.
What do you guys think? For the record, I'm a man.
