More than one person may find this question ridiculous. It all depends on the personal taste of each one, in addition to your preferences and needs.
Although When it comes to dressing, personal tastes tend to take precedence over any other consideration., common sense should prevail at all times.
First things first: they serve the same purpose, but they never go together!
The reasons for wearing a belt and suspenders at the same time are several. But without fear of being too radical and conservative, none with validity.
Beyond the fact that both garments fulfill the same function, wearing both accessories is something that never looks good.
Suspenders: synonymous with elegance
Many people recommend skipping this accessory when wearing a shirt without a tie. It is also not recommended for use with jeans or informal styles.
However, from time to time relaxing and going a bit out of the box doesn't hurt. Without forgetting common sense.
For adjusting dress pants, suspenders are ideal. Unlike belts, they will not create wrinkles or pockets on shirts.
At the beginning of the XNUMXth century, it was an act of bad taste to wear them without a jacket and expose them to the naked eye. Something equivalent to showing underwear in public. Today that conception has been left behind.
Belt: the casual friend
Belts, with very few exceptions, it is more common to use them with the everyday clothes.
Jeans are not only made to wear the belt, but also to show it off. With jeans it is very good to crown the belt with a powerful and striking buckle.
The discreet belt models are suitable for casual combinations. This is the case of jeans or cotton pants with a short-sleeved shirt. Even for a suit without a tie, it is the ideal companion.
Those who do not get along with the suspenders and must dress in a closed suit, may well resort to the belt. Of course, to choose between suspenders and a belt, it must be an extremely discreet, almost invisible model.
