Select Dress Pants Size
Dress Pants Waist i

Select the waist size you normally buy your dress pants in. Note that the actual circumference of the waist (that will show in the size chart) will be larger than the selected size, as this is normal for pants sizing.

Dress Pants Inseam i

Select the normal inseam length you would buy your dress pants in. The inseam length is the distance from the bottom of the crotch of the pants to the end of the leg opening.

Fit i

Extra Slim is our slimmest fit around the hips and thighs, with a distinct taper from the thigh down to a narrow leg opening. Suggested for guys that are either particularly skinny, or more average sized but want an aggressive slim fit.

Slim is our modern, office appropriate, most popular, slim fit. Slim but not tight with a taper to the leg opening. Suggested for average sized guys that want a clean modern look that’s not too tight.

Straight is similar to our Slim fit, but with less taper at the leg opening for a wider “boot cut”. Suggested for guys that want a relatively slim fit, but a leg opening that will cover more of their dress shoes, or fit over their boots.

Athletic is roomy in the seat and thighs, but tapered to the knee and leg opening. Designed for guys with larger thighs and buttocks relative to a smaller waist. If you’re an athlete that wants a modern slim fit, but “Slim Fit” pants are generally too tight around your legs, this is for you.

Classic is roomy in the seat and thigh with a leg that stays straight from the mid thigh down. Suggested for guys that want a more old-fashioned, roomy fit and a leg opening that will cover more of their shoe.

Product Info

An incredibly soft flannel trouser for the fall and winter. Woven from premium Italian merino wool from Vitale Barberis Canonico, this luxurious mouliné flannel is brushed to perfection for a smooth and sophisticated yet cozy finish that will keep you warm through the colder months of the year. The static-like effect of the varied grey mouliné is achieved by twisting yarns of different shades together to create depth and movement throughout the fabric. This trouser is a great option for a grey that’s a little different.

  • excellent

    Gianfranco in Brentwood, TN

  • Nice warm heavier winter trousers.

    Douglas in Skillman, NJ

  • I am a huge fan of merino wool clothing. Merino wool pants are pretty rare, so it's amazing to have a selection of perfectly fitting merino wool pants. I am also a huge fan of the no belt-loop option which makes the pants look so much more classy and earns me lots of compliments. Please keep the merino wool fabrics and styles coming...would love to see more casual-style pants in lighter merino wool weaves.

    Leeor in Northampton, MA

  • Shattered my expectations in regards to fabric, quality and design. They feel like pajama pants but look so sharp, any man needs these for the winter.

    Zachary in NEW YORK, NY

  • Love the variation on straight grey flannel. The more complex look and texture makes your typical grey pants and blazer outfit something noticeably more interesting.

    Thomas in NEW ORLEANS, LA

  • It is a nice gray color that is versatile that will mark with a number of shirts.

    Brian in Burien, WA

  • Fantastic quality. You should have an internal phone pocket though as the pockets are currently too roomy.

    Ryan in Summer Hill, NSW

  • Very nice, heavy fabric. Unique look, perfect with cuffs.

    Kevin in DENVER, CO

  • Lovely fabric. High quality, easy to care for, and perfect weight for cooler temperatures.

    Timothy in WASHINGTON, DC

  • This is my favorite gray flannel in the Proper Cloth line-up. It can dress up or down with ease.

    David in Phila, PA

  • I especially like the side loops which is the first time I have had pants with these. The flannel is very smooth to the touch and the pattern of the pants is truly unique.

    Kenneth in Belle Mead, NJ

  • Fabric is hefty and luxurious, semi-solid but with visual interest from the different thread colors.

    Vivek in Carmel, IN

  • Smart pants software is unbelievable and precise.

    Ryan in KANSAS CITY, MO

  • The fabric is exactly what I wanted: it feels like high-quality material with no corners cut. The design with no belt is what elevates the product into a dream garment. The light cream colour is calming and pops paired with darker blues and navy shirts.

    Ryan in Summer Hill, NSW

  • If you have to wear dress pants in the winter, these are a must!

    Alex in Palm Beach, FL

  • The fabric was wonderful and felt extremely nice. The quality was excellent. I wanted to be able to keep them.

    Colin in Oregon, WI

  • Material is high quality and well constructed, but in comparison to the my first pair, an excellent pair of winter-weight wool trousers it doesn't feel like quite as good of a value.

    Nathan in SAN DIEGO, CA

  • The fabric is comfortable yet elegant.

    Celeste in Los Angeles, CA

  • Very high quality fabric.

    Karl in Sweden, Skanör

  • Spectacular weight to fabric.

I have a custom shirt size already, can you use that to create my first suit/jacket/pant size?

It is difficult to predict suit/jacket/pant sizing from shirt dimensions alone as the pattern, range of motion requirements and fit preferences vary between the different garment types.

To create your first suit/jacket/pant size, we recommend updating your Smart Size quiz answers.

  • Work with our team to determine what changes need to be made, and have Proper Cloth alter the garment for you or remake it in a new size.
  • Return the tailored clothing to us and have it remade in a different standard size. (For example, if you ordered a 40 Regular Slim Fit, we could remake it in a 41 Regular Slim Fit.)
  • Return the tailored clothing to us for a full refund.
Do you offer rush delivery?
