so i ordered my jacket online and it arrived yesterday. i ordered a medium because that was the smallest size they had for that model. the arm length and around the waist both fits perfectly, they are adjustable. i am a little skinny and around the chest, back, and side areas its sorta loose. ill be fine right? or does it has to fit perfectly all the way around?

 

Should be fine. Gives you more incentive to bulk up your chest.

 

What jacket did you get?
