You know when you go for years without noticing something, but then someone points it out and you just can't un-see it? Yeah, that's happened to us with these old photos of Prince Charles and Princess Diana.As pointed out in two Twitter posts by two separate accounts recently, it looks very much like Prince Charles is taller than Princess Diana in all these photos, doesn't it?But the thing is, Diana was the same height as Prince Charles.And a quick Google search confirms it, Prince William and Prince Harry's parents both measure in at approximately 5'10".One Twitter user, @LuciHoneyChurch, noted that she recalled "the lengths to which the couple went to disguise #LadyDiana's height."Height aside, one thing is for sure: The couple was always dressed to impress.
