While everyone will be looking at Meghan's wedding dress on her big day, we can't forget about Prince Harry's ensemble. The royal is expected to wear his military uniform (he was in the forces for 10 years) much like Prince William did on his own wedding day. He and Prince Harry both wore custom-made sweatproof military attire when Prince William said his "I dos" to Kate. We have a feeling the men will look extra spiffy on May 19.
