Accesorizing as a guy can be limited but not imposible. If you're not big on accesories, just keep it simple. Try elevating your outfit with a nice leather watch and a matching belt. Bonus points if you add a simple gold chain.
But really I think most- if not all, accesories are gender neutral. It all depends on the base outfit, the accesories are more like frosting for your cake.
If you're not scared of accessories, elevate your oufit with some jewelry. This is another example that accesories are gender neutral. My only two cents is to keep it classy. Less is more when it comes to formal events.
If you don't mind the sensory overload, layering necklaces is a great way to elevate any outfit. These are some combos I love because they're soft and tasteful
Don't be threaten by a red lip moment. Sometimes all you need is a pop of color to bring all of your outfit together.
