I am 5' 3'', size 18, 235 pounds and ordered the XX-Large. I ordered the WB829 which seems to be a longer length, if you are looking for a skirt that is an appropriate length chose the one with the number WB8 name of the color! This skirt fits around my hips and can be worn high on my waist. The skirt sits just above my knees and is an appropriate length for work. I probably could have sized down to the XL. The skirt flares out right around my midsection and disguises my tummy, it looks very slimming. I plan to purchase more colors!
