Depends on the specific design. They almost all have flaws. I hate when the leotard is drawn like in your OP. Chiang did very well on the new 52 run with it, for example. But that costume had stupid and unnecessary jewelry. I hate the current rendition of the skirt in Rebirth because of how the pleats are drawn and the boots are disgusting. Fabok's design was too bulky.
It should not be this hard to make a fully good design.
>>92884074Pants CAN look ok, like the design during JMS's run, but I still think they're a Donna thing that doesn't belong on Diana. Like how you wouldn't give the crab mask to any GL who isn't Kyle.
