Sleeves are such an important part of clothes as it is one of the first things you see in a garment. They should fit properly and be comfortable to wear as well. Sleeve styles vary greatly with time and fashion.
Fashions of sleeves come and go. One moment a particular sleeve may be in fashion but then they disappear completely for decades to resurface later and become a rage again. I remember wearing loose puff sleeves in my teenage years as it was in fashion; now I cannot imagine wearing them, one because it absolutely kills my body shape and two they are luckily not in fashion
