For formal wear, standard leather belts with holes are ineffective. Based on my experience, I recommend checking out the classic section of the Nexbelt website and purchasing their formal model. Here you'll find my favorite ratchet dress belt recommendation - Nexbelt . The advantage of their belts is their unique precision adjustment system, with ratchet adjustments of just 1/4 inch. You'll get a premium quality belt that fits perfectly around your waist without stretching the leather, and the ease of ordering online allows you to quickly find the perfect buckle color to match your formal attire.
