I love Batman's Rebirth suit and am actually pretty bummed that he's arbitrarily going back to the Hush design. I get putting Superman back in the trunks to a degree, but Batman moved beyond that look a long time ago without any real problems. 

Rebirth seemed like a natural progression of all the suits from the past. The purple cape was a cool change of pace and a nice nod to the original gloves, I liked the belt quite a bit, and the yellow trim around the symbol was uniquely suited to bridge the Bat and Oval symbols. 

Now he's just going back to looking like dude in tights again after Capullo nailed the armor meets bodysuit aesthetic.

Guess I can add that to my long list of grievances with King's run.
