Skinny jeans are definitely more for their look than their comfort, otherwise I'd probably be wearing sweat pants (as it is, I don't own a pair of those). But skinny jeans are not that bad--as long as you buy ones that aren't too restrictive, there will be plenty of room for one's "junk", even trunk junk.
Don't confuse hipsters with proper millennials. The legit millennials wear repetitive stuff, like; worn sketchers, light blue jeans, and black turtlenecks. Hipsters wear heavy facial hair, sunglasses and manbuns. The millenial will have a short 90's-do, thin spectacles and a light stubble-beard.
I can't keep it straight, but I think I understand. There are the usual "geek culture" Millenials and then there are the "artsy pompous hipster fashion" Millenials. However, both are "BS" on the normal scale for normal people.
