For the tall gent
If you’re closer to the ceiling than most of your peers, then you should go for a denim that’s got a bit of stretch. You should avoid, at all costs, any flare-type denims like bootleg cuts as these will only work to over-emphasize the size of your legs and your height.
Rather go for something a lot more slim fitting, and if you’ve found that you have a bit of a big waist, then for increased comfort – go for a jean that’s a higher rise.
For the thin gent
If you fall more on the thinner side of the scale, then you should never wear a baggy jean; you will look like you’re drowning but you also don’t want a jean that’s too tight as this will highlight your thin figure.
This is why the skinny gent should always opt for a slim or straight fitting denim (not skinny) as this will not be to big nor too tight.
For the average built gent
The average built gent is probably the luckiest. Your neither tall or short, big or skinny – you’re literally just the perfect and average size. Because of this, you can get away with quite a lot, not only with your denims, but your entire wardrobe.
With this in mind, if you’re wanting to go for a more modern look, then your best bet would be to go for a slim, straight cut jean. You could even get away with a regular fitting jean, but just make sure that it fits, and doesn’t look like it was draped over your hips.
For the short gent
Short guys that would like to add an illusion of height to their build should go for jeans that are slim fitting, you could even go for a skinny fit. And it’s also important to find a tailor you like and that you can afford and have him/her on speed dial. Chances are you’ll struggle to find jeans that are a good length for your height and unlike tall guys that will constantly have to add length to their pants, shorter guys have it easier because they only have to hem the pair of pants.
For the muscular gent
As a muscular gent, buying clothes and getting dressed is not the easiest things to do. There’s a lot to consider with your clothing choices with regards to your muscular build. This is also true when it comes to picking your denims. Chances are you have big thighs and this often makes it hard to find pants that won’t be tight in that area.
This is why, when it comes to jeans, you should always avoid the slim and straight cut jeans and rather go for a regular fit that’s a lot looser and not leg-hugging. You might feel that a tighter fit could show off your muscles, but it’ll only raise brows.
