In fact, there's only one known butterfly that has cracked the code for making a true blue pigment.

And that wasn't out of disrespect to any of my Carolina guys -- they all know I'm a true blue Carolina guy to the heart.

If you're looking for something bolder though, you could go for a shoe in a true blue, say for example, a whole cut oxford or maybe a monk strap shoe, these would go well with a gray suit.

如果你正在寻找更大胆的东西，你可以选择一双真正的蓝色鞋子， 例如，一双全剪裁的牛津鞋或者僧侣绑带鞋，这些鞋与灰色西装很相配。
