The goal in cold weather is warmth without hiding the outfit underneath, layer around a piece like Aria, not over it.
Worn Open, Always
A blazer or jacket closed defeats the entire purpose of what's underneath. Worn open, it adds warmth and keeps the top visible.
Fitted Over Bulky
A structured leather or faux-leather jacket adds warmth without the volume a puffer brings.
Use Coat Check
Layer heavy for the walk in, shed it once you're inside. It's the actual workaround most people use and nobody talks about.
