Here’s a good example of how to wear several different dark neutrals with a colour. The visual result is not as dark as the super dark head-to-toe look that’s on trend, although the vibe is related. The point is to encourage you to put similar darks together with items in your wardrobe. The darks don’t need to match. 

Here, black and three types of brown are combined with a deep bordeaux red. A black tiered midaxi skirt is combined with a tucked bordeaux pullover. A warm chocolate brown blazer tops the pairing. A cool and darker chocolate brown pair of western boots ground the outfit. A gingerbread belt is added for textural detail and interest. It’s the third brown and a lighter one. Not sure whether the belt will stay put sans belt loops, but you get the idea.

Feel free to switch out to the skirt for black pants or jeans, the black for navy, the browns for greys, and the bordeaux for forest green or eggplant. If you enjoy wearing dark outfits like this, experiment, and see what you come up with. Hope to see your renditions on the forum.
