  • Garment measurements are in inches.
  • Trousers are delivered with a finished hem (plain hem style) at the above mentioned inseam lengths.  See "Alterations" notes below for guidance on how much the inseam can be lengthened or shortened by your local tailor.
  • Instructions for taking measurements are provided below.  When measuring at home, please follow these instructions as closely as possible to ensure you are measuring in a similar way:
    • WAIST: With the trouser fully fastened and laying flat on a table, smooth the fabric as much as possible to remove slack.  Run the tape measure along the very top edge of the waistband from left to right.
    • FRONT RISE: With the trouser fully fastened and laying flat on a table, place the measuring tape at the crotch of the pant (between the legs, where you will see a seam joining the front of the leg to the back of the leg) and run the tape straight up the front of the pant, along the fly, up to the top of the waistband.
    • THIGH: With the pant laying flat on a table, pick which leg you wish to measure (either one is okay).  Pull the other leg outwards and away, which will allow the leg you are measuring to lay as flat as possible with as little slack as possible.  Smooth the fabric of the leg you are measuring as much as possible. Place the measuring tape at the crotch of the pant at the highest point of the inner leg (this will be slightly below where the front panel is stitched to the back panel).  Measure straight across to the outer edge of the thigh as horizontally as possible. 
    • LEG OPENING: With the trouser folded along its crease, lay one leg flat on a table.  Place a tape measure at the bottom opening of the pant leg and measure straight across. 
    • INSEAM: Lay one pant leg on a table.  Place the measuring tape at the crotch (where the front panel is sewn to back panel / left panel is sewn to right panel).  Run the measuring tape along the inner seam of one pant leg down to the hem.  The tape should be gently curved along that stitched seam, following its line as closely as possible. 
  • The above measurements apply to the following Brooklyn Tailors styles:
    • BKT50 Tailored Trouser
    • BKT50 Tuxedo Trouser
  • While the above-mentioned styles have similar overall measurements and fit, each have different construction, stylistic details, and attributes that will affect the way the garment drapes and shapes the body.  Check each individual product listing for additional details specific to that item.



As with most tailored clothing, our suits are constructed in a way that allows them to be altered by your local tailor to fine-tune the fit to your needs. While a wide array of alterations can be performed on our trousers, below is a list of the most common alterations, along with a rough approximation of how much the garment can be taken in or let out. The below list should only be considered a rough guide, as specifics are up to the discretion of your tailor.

  • WAIST:  The waistband can be taken in up to 1.5 inches approximately. It can be let out up to 1 inch approximately.
  • SEAT / HIPS:  The seat can be taken in up to 1 inch approximately. It can be let out up to 0.75 inches approximately.
  • LEG: The leg (thigh, knee, leg opening) can be taken in up to 1.5 inches approximately. It can be let out up to 0.5 inches approximately. 
  • INSEAM: To adjust the length of the trouser, the inseam can be let out up to 2.25 inches. It can be taken in (shortened) as much as desired.
