Replying to Why these big clothes?

So i had argue with my mom that she wont pay half of the cost of a new baggy jacket. She explained that the lenght has no purpose, you cant see what the skier is doing in the air because of the big clothes (wtf, mom) and the lenght costs more money (doble wtf mom!?) and it's harder to do tricks in it.
(idk where she has get these into his mind)

So what are some good points why baggy clothes are better. And why do you wear baggy stuff yourself?

And no, i'm not a gaper who just got his first twintips and has started skiing, i'm been skiing for 11 years. I'm just short of money and need to half the cost of my next jacket with someone.
