Here's a perfect way to wear gray (or any color that no longer suits you). I totally love the way the pink draws attention to your face & your middle (without showing much). Personally, I would replace the turtleneck with the same color and type top.
This is the kinda outfit I can imagine a really sophisticated looking lady wearing. A girl with her hair pulled back in a really tight ponytail and black sunglasses. Then she'll be dramatically taking of her sunglasses while wearing this outfit. Love it
This business professional outfit works very well as it has the timeless colored white blouse with a simple pencil skirt. It is the proper length and classy. It is a clean look and shows that you are there and mean to do business.
