There are styles that will make them look worse, but none that make them look good.  I disagree, a decorative  burqa could be quite attractive with some suitable wire or hoops to help maintain the shape. It would turn a collection of fats into a kind of slow-moving tapestry display.  Alternatively, as fatties like being in the water, their appearance would be greatly improved by some concrete footwear. If they wore that, I'd be happy for them to be naked.
