Why is it more acceptable for a woman to wear leggings outdoors than sweatpants?

Let’s say you make both look presentable. I know it’s not really fashionable but sweatpants are comfier. If you wear cool sneakers and leather jacket, makeup and small jewellery making it look more presentable. Why would it be more looked down on as ‘sloppy’

Assuming both are for casual going out. Not for a restaurant or date
