Let’s clear something up: Quilted coats aren't really different to puffer coats. However, for the sake of clarity, the quilted coats I'm going to refer to, especially in this context, is outerwear that has an unmistakable stitching, often in a diamond format.
To give you a better understanding of what this sort of outerwear looks like, you need only look to Queen Elizabeth II. That's right—HRH is a fan of this style of jacket. While it's often associated with people who spend their weekends in the Cotswolds, this surprising trend is suddenly everywhere this coming season.
