Size Guide

We understand the importance of receiving items that fit and compliment your body shape in the best way possible, therefore, we've created the below size guide to help. In order to minimise returns and wasted orders, please review the size chart if you're unsure on what sized garment to purchase from us.

Ideally, you should measure yourself first. If you already know your measurements, feel free to jump down the page and view the relevant size chart by clicking one of the links below:

If not, take a quick look at the illustration below, grab your measuring tape and make a quick note of your measurement numbers. For tops, you only require chest, waist and hip measurements. For bottoms, measure your inseam, hip and waist. We've included tips on how to measure each area below.

size guide


Take your top off and place the start of the tape measure on the front fullest part of your chest (either the left or right side) and secure it in place with your thumb or fingers so it does not move. Then wrap the tape around the back of your body until the other end of the tape measure reaches the initial starting point where your finger is.

The tape measure should travel under your arm pits and should be kept as horizontal as possible. Try not to let it dip down on your back as you may lose some vital measurements here as your upper back is generally fuller than the lower back. Where the tape measure points meet, take this reading and this will be used as your chest measurement.  


The waist is situated just above your belly button and should be measured at the narrowest part. You can easily identify this if you're measuring yourself by standing in front of a mirror.

Take your top off and place the start of the tape measure on your front body and wrap it round the back of your body. Be sure to keep the tape measure as horizontal as possible until it meets the initial starting point. This will be your waist measurement.


The hips are located further down the body as per the illustration above and you should measure the widest/fullest part. Stand with your feet together while measuring. If you're still confused, imagine wearing a pair of bottoms, the waistband of those bottoms will usually sit just above your hip bone so look for the widest part of your body below the waistband of your bottoms or shorts. It's likely to run across the top of your buttocks too. 


The best way to measure the inseam is to find a pair of bottoms that fit you well and have the desired length you require. The inseam is then measured from the crotch seam of the garment down to the hem (bottom). This is not to be confused with the inside leg measurement which is actually taken from your body instead of the garment. 

Quick Measuring Tips:

  • Get someone else to measure these for you to make it easier and more accurate
  • Measure the area twice to ensure the numbers are correct
  • If you don’t have a body measurement tape, grab one from Amazon Here

Size Charts

Please note that all measurements in the size chart tables below are in inches.

t-shirts and hoodies

If your body measurements result in two different suggested sizes, order the size that is recommended by your chest measurement. If you fall in between sizes, for example, a 38 inch chest falls into size S and M, we would recommend going for the bigger size.

Size S M L XL
Chest 36" - 38" 38" - 40" 40" - 42" 42" - 44"
Waist 29" - 31" 31" - 33" 33" - 35" 35" - 37"
Hip 34" - 36" 36" - 38" 38" - 40" 40" - 42"


If you're on the borderline of two sizes, say for example you have a 31" waist, we'd recommend purchasing the larger size. If your body measurements for hips and waist result in two different suggested sizes, order the size that is recommended by your hip measurement.

Size S M L XL
Waist 29" - 31" 31" - 33" 33" - 35" 35" - 37"
Hip 34" - 36" 36" - 38" 38" - 40" 40" - 42"
Inseam * 30" - 32" 30" - 32" 30" - 32" 30" - 32"

* The inseam for the joggers is fixed and will fit perfectly for anyone with an inseam between 30 and 32 inches. This will cater for the majority of people.

If you fall slightly under the range, you will simply have a slightly baggier garment. This won't be an issue unless you are significantly under. If you're over the range, depending on how far, the higher up the end of the trouser leg will ride. Again, if you're only slightly over, it shouldn't be an issue.

If you're significantly over, perhaps the style may not be for you. If you're unsure you can always try it, and then use our Returns Process if it's not quite right for you. 


The same applies here as for the joggers. If you're on the borderline of two sizes, say for example you have 31" waist, order the bigger size. If your body measurements for hips and waist result in two different suggested sizes, order the size that is recommended by your hip measurement.

Size S M L XL
Waist 29" - 31" 31" - 33" 33" - 35" 35" - 37"
Hip 34" - 36" 36" - 38" 38" - 40" 40" - 42"

Using the size chart correctly

Using our size chart is super simple! Once you have your measurements ready, locate the chart for the specific garment you'd like to check the fit on. Now check the very first column of the chart and start on the second row, the cell below 'Size'. Take your already calculated number for this measurement and move across to the right of the chart and find which number range this falls into.

Once you've found the range your measurement number falls into, check the column header that the cell correlates to at the top, and this will tell you your recommended size. Replicate the same process with your other 1 or 2 measurements to check that they also fall into the same recommended size. 

A quick example

If you're buying a t shirt and your chest measurement is 39 inches, locate the chest measurement row on the left hand side of the table, then move across to the right of the chart until you find the number range that the number 39 falls into. In this example, it falls under the column heading medium and you would therefore look at purchasing a T-Shirt in size M. 

Falling in between sizes explained further

There's a chance that you may fall in between 2 different recommended sizes on the chart. For example, our medium (M) sized t shirt has a 38-40 chest range and our large (L) sized t shirt has a 40-42" chest range. If you're chest measurement comes in at 40" you will fall into the medium and large sizes.

It's no big deal and the resolution is simple. We recommend going for the slightly larger size to ensure you will have no problem with it being too tight. If it's a little loose, please also take into account that due to the nature of the fabric being used (cotton), after it's first wash it will become slightly more fitted so this is also why we'd recommend choosing the larger size.  

Got two different recommended sizes?

Again, not a big issue at all. Let's take the t shirt example again. Say your chest measurement of 39 inches recommends a size medium on the size chart, but your waist measurement of 34 inches recommends a size large, always purchase based on your chest measurements recommended size. In this case, a size medium should be purchased. 

For T-shirts, chest measurement always takes priority so buy based off the chest measurements recommended size. For joggers and shorts, hips will take priority and you should purchase the recommended size based off your hip measurement and not your waist.

Not happy with the fit?

No problem, please feel free to return the garment to us by following our Returns Policy and we will happily exchange it for a new size.

One last note about the fit of our garments

Sole Ambition garments have been designed and manufactured to be slim and fitted. This means that the garments are not loose, nor are they tight, they have been designed to find the perfect balance while minimising excess material or bagginess, and providing a flattering aesthetic look and style. 

If you're looking for a more over-sized style and the garment description does not state that the style is an over-sized fit, please consider purchasing one size larger than you would normally order.
