I need help with a snowboard jacket and pants!?

i need to get a jacket and pants before the season starts. i dont know what size i should get though because i want baggy stuff and im not sure the size of my old stuff because i gave them away. it sounds funny but im trying get a travis kennedy vibe with my clothes. BTW im 5'7" and 126lbs and i have a size 30 waist. please give me sizes that will look baggy but not overdone to the point its falling off of me. THANKS!
