It’s easy to sit back and just tell everyone to commission their own custom garments from Bespokuture. However, it’s not a luxury that everyone can afford. So let’s take a look at how a suit should fit.
The Fit
The first thing to understand is that in order for some areas to fit well, others may be slightly off. Often times a consumer will purchase a garment which fits the chest or stomach region, but may miss a key fit elsewhere. This is quite common since suit companies will try and create generic sizes that fit as many customers as possible. And with said, let’s take a look at the two most prevalent and commonly improperly worn pieces.
The Jacket
A suit jacket or blazer will be the most immediate item that everyone sees. Therefore they will quickly notice the fit of the chest and stomach in your garment. Although slimmer fitting pieces are ubiquitous now, there seems to be a blurred line separating slim fit from simply too tight. In case you’re unsure, here are a few tips to keep you away from the danger zone. 
If the jacket pulls away from the chest or buckles mid-lapel, the chest is too small. It’s also a giveaway if your shoulders are bulging out towards the front of the jacket. Similarly, if the edge of your jacket buckles at the top of your arm, then the shoulders are too wide.
However, this does NOT mean that anything is wrong with your body. It’s just that ready to wear (RTW) suits are made for the masses and have a much straighter shoulder line with very little break.
If your shirt sleeve falls to your thumb knuckle (base of the wrist) then your jacket sleeve should rest slightly above that. You should show a minimum of 1/4″ of the sleeve but no more than 1″, and that’s if wearing French cuffs. The jacket length should fall right at the bottom of your crotch line or at the bottom of your front pockets if wearing slacks. This will allow for a more modern look without coming up too short. The Pants
Pants are unfortunately an afterthought for most men, especially when it comes to dress pants. Especially since we are navigating through a period of slimmer garments and are coming across more and more gents with ill-fitting pieces. A streamlined tapered pant shows well, but it should never be too tight. So tight that you can’t sit down or fit anything in your pocket.
However, today’s gents are showing a bit more ankle which was brought about by Tom Ford and the European influence. These days showing skin is okay, but only to a certain extent. We all have ankles, and that’s fine, but people may not want to see the hair on your legs whilst seated in a meeting. It’s similarly uncouth to see dress pants pooling at the bottom of one’s leg!
This happens to be the waistline. Simply put, if you can’t wear your pants without a belt, Your Pants Don’t Fit! Pants with waists that are too large lead to material bunching. This gives you a disheveled appearance. Instead, opt for no belt loops with waist adjusters and suspenders (braces). You can also have the pants altered at the problem area. Above all, understanding these nuances will completely change your relationship with suits, especially now since you know how a suit should fit.
