The outfits are a concern solely as part of an overall mentality which causes the lack of quality and lack of consistency with the OT.
The fact that the prequels are obviously not as good as the OT don't mean that every single aspect of the movies needs to be bashed. Almost every posts, with the exeption of yours, brought an argument about why the costumes are looking the way they are. If you don't like the style, you don't like the style, but the costumes are one the few elements in the PT that were done for good reasons. IMO.
I think your problem is maybe more that there are too much Queen, senators, politicians etc... in the PT. And I'd be totaly with you on this one. But once you have this sort of characters, you just can't dress them in rags.
The lightning of the movie is also big part of the way we look at the costumes. Take those same clothes in a dark environment with no oversaturated color and maybe you'll find them cool.
