When someone's fit is peak, they are very well-dressed and/or groomed.

A fit can be peak both if it is casual but clean or if it is formal and well-fitting.
Have you seen Jaime today? He has his hair gelled back and matched his belt to his shoes; that fit is PEAK, man.

Cassie's in a hoodie and khakis, and lord is that fit peak.
