The products we sell are designed by us to fit tall slim and athletic builds, and so aren't the same as the sizes you'd find in a big and tall store. Our sizes are the same as regular high street sizes, but longer!
You'll find general advice on how our products are sized here:
On each product page, we publish detailed sizing, including measurements, so you can compare them with something you already own, that fits you well.
We also supply detailed measurements for the models we use, so you can compare them to your own measurements for guidance.
And because we're tall guys too, and understand the struggle, you can always contact us if you need to know more.
