Replying to What size pants should i get

Im about 5’8 and weigh 115 (ik im skinny bruh) im wondering what size pants i should get for skiing. When im just out and about i wear size 33” pants and they are somewhat baggy but i would like to go omega steeze for this upcoming season. Would 37” be unreasonable? I also don't want to look like i have a shat diaper under my pants and i still want to be able to move my legs like a normal human being. Also, whats the best way to keep ur pants up?
