Hi Sarah,
Thanks for reaching out! We're really sorry to hear that your Yaks aren't measuring as expected, we understand that it's sometimes a little difficult finding the best fit while buying online and we understand your frustrations if you checked against our sizing chart before purchasing.
If you'd like a little further assistance for future orders and you're comfortable doing so, you could send over your body measurements and usual clothing size across to us and let us know which product you're looking for. That way we can look at our charts and specs and recommend a size for you.
All the best,
Kat
