For a gift for that man in your life, or if you're looking for pants for yourself, you might need some suggestions to help you on your way to a great pair of britches.  A few things to remember: your budget is important. It's very easy to spend a few hundred dollars on tastefully ripped jeans that will last six months before disintegrating, and if that's your thing, then by all means go for it. But when considering a budget, remember that most pants are around $40, but obviously, there are less expensive and more expensive pairs--it just depends on what you need and what you can spend. When buying pants, always try them on; you want to make sure that they will fit, and just think of new pants like preparing for a long trip--you want to pack your junk well!  With men's pants, there are a lot of styles available to you, and it really depends on your personal taste!

Fit First

Most men's pants are sized with two numbers: waist and inseam measurement, in that order.
Measure your waist by wrapping a tape measure around your torso wherever you want your pants to fall. Keep a finger or two between the tape measure and you, so that you have a bit of breathing room and space to tuck your shirt in.

If you're going the classic and respectable route, measure at your proper waist, where your body creases when you lean to the side. Tip: find your belly button. That's your waist level.
Younger and trendier men often wear their pants  lower, along their hips. This is a riskier way to go, as you may show off parts of yourself intended for private use, but if it's really where you want your pants to fall, use that measurement.

A smart man will never leave his gut hanging out over his pants. Don't give in to pride and insist that you wear the same size jean you wore in college--let go of your delusions and buy pants that fit.

To get fancier, if you want to calculate the rise of your pants, it's the distance from the crotch to the waist. It will dictate how high your pants sit. Many pants will come in low- , medium-  and high-rise  options. If your pants are above your waist, that's high rise, at your waist is medium and below your waist is low rise.

The rare exception of casual pant will be sized S  -M  -L  -XL .   Usually this type of sizing is only used for casual pants like sweatpants  or hiking pants .   If you know your waist and inseam measurement, you should be able to tell which size S-M-L-XL to pick.
Style

When buying pants, check for comfort . Sit in them. Walk in them. Still feel good? Good.
If they are too long, take them to a tailor.
Make sure pants coordinate with the clothes already hanging in your closet. Your pants should work with your belts , shoes , and shirts .
How do you want to keep your pants up? You can have suspenders  or you can have a belt. You cannot have both.

Your socks should be in the color scheme of your pants, not your shoes.

Cuffs  are a mature and polished look. Cuff length should never exceed an inch and a half.
Straight legs  always look good and flatter the most heights and builds. Skinny guys can get away with tapered legs . Flared pants  only work on jeans--and only on tall guys. Baggy pants  are rarely a good idea unless you have your own rap label.
