I wear dresses that are knee length because I think 'I can be fat and wear horrible clothes or I can be fat and wear this nice thing', but for some reason I don't wear jeans.
My legs are massive. I usually wear a size 18/20 top/dress. I just measured my legs and it's 27 inches round the middle of my thigh and 19 on my calf! 
I do however need casual stuff to schlep about in and to wear to the park/shops etc.
Am I just too fat thorough? Will you be able to see my cellulite?
