Our grandmother always said, “measuring is knowing”. Of course holding your breath whilst wearing one of our suits is an option, but far from ideal. So; let’s see what our experts have to say about our sizes and measurements.

Men's Suits

Our men’s suits are available in the standard UK suit sizes ranging from 36 to 52. However, we strongly advise you to take some time in order to measure yourself, or have someone else measure you up to ensure you get the correct size.



Men's Suits
UK Size Chest size Lower waist size Inside leg size
36 < 40” < 33.5” < 32.7”
38 < 41.5” < 34.5” < 33"
40 < 43” < 35” < 33.5”
42 < 44.5” < 36” < 34”

50 < 53” < 43” < 35”
52 < 55” < 45” < 35”


PLEASE NOTE: OppoSuits have a slim-fit design. When in doubt between two sizes, we recommend you to pick the larger size of the two.


How To Measure

Measuring up your chest size is the most important part as it is essential to get the right size jacket. Identifying your chest size should be achieved by measuring at the widest part of your chest with a tape measure.

The lower waist is measured around the part where you normally wear trousers, just three fingers below the height of your belly button. For the inside leg size, let someone measure you from the highest point from the inside of your leg down to where your heel hits the floor. Hold the tape measure alongside your leg, keep your legs slightly apart, and do not wear shoes while doing this.

Once you have your measurements, please compare against the table above to identify the correct size. If your chest size falls into a different size category compared to your waist, all you need to do is select the jacket sizing you require. The trousers are ready to go in their stated size but if you need them taken in or need a little extra added, the design allows for a tailor to adjust the waistband and side seams two sizes either way.

Trousers length

Our trousers are slightly longer in length than your usual suit. This has been done on purpose so that the pants looks better with sneakers and other casual footwear. The extra length can easily be shortened by your local dry cleaners or granny with suit shortening skills in case you find the trousers too long.




Women's Suits

Our women’s suits are available in the standard UK suit sizes ranging from 8 to 20. However, we strongly advise you to take some time in order to measure yourself, or have someone else measure you up to ensure you get the correct size.

How To Measure

Please take a look at the visual of the woman next to the size chart above and follow these simple steps;

  1. Bust size
    Measure yourself with a measuring tape just underneath the armpit and make sure you don’t strain the measuring tape too much while doing this. Also please make sure the tape is held in a straight horizontal line.

  2. Waist size
    Measure yourself just around your belly button and please make sure the tape is held in a straight horizontal line.

  3. Hip size
    Measure yourself around the widest part of your hips (often this is around 8 inches from your waist) and please make sure the tape is held in a straight horizontal line.


Once you have your measurements, please compare against the table above to identify the correct size. If your chest size falls into a different size category compared to your waist and/or hip size, we advise you to select your size based on the skirt size you require. To improve the fitting of our product, we’ve added an elastic insert in the waistband of the skirt in a classy way.



Boys' Suits

Our boys’ suits are available in the standard UK suit sizes ranging from 2Y to 8Y. However, we’d still like to advise you to take some time in order to measure the boy the suit is for, to ensure you receive the correct size suit.

    Measuring up the chest size is the most important part as it is essential to get the right size jacket. Identifying the chest size should be achieved by measuring at the widest part of the chest with a tape measure.

  2. Waist Size
    The lower waist is measured around two fingers below the height of the belly button and please make sure the tape is held in a straight horizontal line.

  3. Inside Leg Size
    The inside leg size should be measured from the highest point from the inside of the leg down to where the heel hits the floor. The tape measure should be held alongside the leg, the legs should be slightly apart and shoes should be taken off.

Once you have the measurements, please compare against the table above to identify the correct size.

If the chest size falls into a different size category compared to the waist size, all you need to do is follow the jacket sizing that’s required. The trousers for our boys’ suits contain an elastic and adjustable waistband. Also, the trousers are ready to go in their stated size but if you need them taken in or need a little extra added, the design allows for a tailor to adjust the waistband and side seams two sizes either way.

Trousers Length

Our trousers are slightly longer in length than usual boys’ trousers, leaving the faster growing boys’ with some room as well. Also, the trousers can easily be shortened or extended in length by your local tailor or by a grandmother with sewing skills.



Teen Boys' Suits

Our teen boys’ suits are available in the standard UK suit sizes ranging from 10Y to 16Y. However, we’d still like to advise you to take some time in order to measure the boy the suit is for, to ensure you receive the correct size suit.
