It feels warmer, softer than all black or all white but still looks clean and modern. It's versatile-as you see here, you can wear all gray in a preppier way, in a more androgynous way, casually or dressed up. All gray lends itself to being worn with other neutral friends like white, brown, or black. All gray also loves to show off with a pop of color like a pink lip or bright bootie.
Here's what to do: pull out everything gray that you own. Put it on together, then add a second neutral color or a pop of color. Done and done!
