Q: What would match a gray blazer?
Both men and women can use these color combinations:
1.You can combine your blazer with its matching pants/skirt and a white shirt. This is a formal business suit with black tie and belt.
You can wear a pair of black heels/ moccasins with this outfit.
A pair of sandals like this is also great to go with the combo.
2.A white long or short sleeve T-shirt and navy pants / blue jeans/ denim shorts can go well with the gray blazer. Wear this outfit with black shoes.
Note: You will look better if the inner top is a deep V-neck or round neck T-shirt.
