Suspenders are fabric or leather straps worn over the shoulders to hold up the trousers. They are elastic and form an X shape or Y shape when worn. They are usually attached to the trousers with a clip to hold up the trousers.
They come in different colours to fit your overall outfit for the day. Suspenders act like the belts that are worn round your waist to keep your trousers fitted, but they are more than belts.
The fact that it is worn over the shoulders makes one more handsome and attractive. The suspended is an attention-grabber because you can hardly walk-by without noticing that the gentleman in front of you is wearing a suspender.
You can wear it over a nice T-shirt, long sleeve shirt or short sleeve shirt with lovely chinos or jeans with a shoe. The trick here is that it must compliment your outfit.
