I like short sleeve coats but if there a reason other than long sleeve coats have a more professional look.
The coats aren't for looks they are there for protection.
I vote for long sleeves.
I didn't even know they made them with short sleeves.
It depends on why you are wearing the jacket. Long sleeves are very important if you are working a grill or other spatter prone area in the kitchen.
However, short sleeves are cooler. If you watch Hell's Kitchen Gordon Ramsey isn't cooking and wears short sleeves, but the 'students' have long sleeves.
Short is good for chocolate and pastry because the cuffs can get in the way.
I only wear mine during delivery and set up and I have not had a problem with the sleeves getting in the way. I do think that the long sleeves look more professional, but during the summer it is definitley HOTTER with the sleeves!!
Mine are long sleeved so I have the option to cuff them or leave them down.
