Amazon EssentialsWomen's Regular-Fit Fleece Straight-Leg Sweatpant (Available in Plus Size)

how do the x sizes relate to uk sizes, 10. 12 etc?

What is the leg length? And how does the sizing work? Sizes available don't match size chart. Thanks.

Are these tracksuit bottoms true to size?. What size would fit a UK12-14?.

What size should I order for uk 14-16, height 5ft 8ins?
