In this regard, how many years does a suit last?
This an impossible question to answer as it depends on how many suits you own and how well you look after them but as a general guide, anything between 3 and 8 years.
Likewise, how many suits do you need for a week? For each day of the week that you'll need to wear a suit, plan to have two suits in your wardrobe. This rule ensures you don't wear the same suit more than twice in one month.
Regarding this, do men's suits go out of style?
An easy choice if you want something that's perfect for the office Monday to Friday, but with a suit jacket that can be put with chinos for a smart casual weekend look. It's safe to say, classic suits will never go out of style.
How many suits is too many?
To summarize, having at least one to two suits will be a safe bet for your wardrobe. Remember that the colors you buy are not the only suits that you can wear. You can mix and match the articles of clothing that you have as appropriate. This will create even more outfits to wear and will help your budget.
