Women who hate other women in minis, jealousy there?

Where does this venomous hate for the mini skirt comes from? Are women really that jealous? Every year, specially when the weather gets warm, there is a crowd of us standing around different places and venues. Then some woman or women walks by in a mini. The lugs start dropping. Some overt, "I would not come out of the house looking like a street walker" "She need to put some close on" Other more direct. "She so hoochie *** all hanging out like that" "*cough* Streetwalker *cough cough*" And the women in the group who are likely to look the worse in a mini are the 1st to start in on those who can shine in them. If these women dropping these insults could ever look that well(and they could, they just don't want to work that hard)they would wear a mini in a minute. So, if they don't want to make the sacrifices or life changes to look good in a mini, why hate on those who do, or can do it with less effort? Why should those in a mini have to come down to their standards?
