See The Hunger Games, Gravity, The Avengers (and its sequels), Man of steel, Cap 2, 300, the Nolan bat trilogy...
My point remains.
There is no need to reduce women to eye-candy to sell things. Yes, it sells to certain people. But, female characters done properly (or ones that are at least not objectified) sell to others and that group is decently sized now. They shouldn't just target WW at the group they think wants scantily clad females. It won't make as much money as it would if they targeted it towards more people.
And if WW's skimpy costume makes no difference to people who buy her comics, why won't they change it? If comics aren't being targeted at a certain group that DC thinks want her to keep wearing a swimsuit, give her some goddamned clothes and call it a day. Azzarello and Chiang are more popular because they are trying to play down the sex factor and I wouldn't doubt they would change her costume if allowed.
