Nah, as with any style, there are always certain clothes that look good and don't. With lolit.a, you just need to shy away from the pink frilly dresses. That doesn't mean the entire style should be thrown out though. Yeah 40 year olds probably shouldn't be walking around in a petticoat and carrying a teddy bear. But, they could probably pull off the more Victorian styled selection.
Caution, I may bite.
