All you need to know about sizes

Ah, sizes! Not always easy to get right, we know. We're all humans, not cookie-cutter people, so we know that what size you buy can vary, between tops and bottoms, with different types of clothes, and even fluctuate over time. That's just life! But we want to make sure we help you get the best fit for you.


In most cases, follow the size you buy on the high street.

Our sizes are based on the size guides used by H&M. So if you know what size you usually buy from them, you can be fairly confident that it will be more or less the same with The Drop by Who What Wear.


We also have a detailed size guide to help. Our downloadable size measurement chart has all the useful measurements for every item in our collection. It details the measurements of the clothes - which will be slightly different to if you measure them on your body. A good tip is to find a similar item you already own, that fits you really well, and measure that. It should help you find what size will be right for you in our size chart.



Find your size in 3 easy steps:

1. Find a similar item you already own that fits you well


2. Measure it on the key measurement points - make sure you get the measurements in centimetres. The measurements in our size chart is measured on an item laying flat. For measurements like bust, waist and hip, the numbers you get when measuring flat are doubled to get the measurement around your body.


3. Look at the size guide for the product you're interested in and pick the size which best matches your existing item.

That's it!


This should hopefully help you get the right fit for you. If you're in between sizes, as a general rule, it might be a good idea to go up a size. Each product will have notes on size & fit for the specific item, for instance if it is a slim fit, if the fabric has a lot of give or if it is a baggy or boxy design.


"Extended" measurements are when the item's waistband is fully stretched, while "relaxed" refers to when it is not stretched at all (as it would be on the hanger).

Detailed size measurements guide

Here are the main measurements for each piece in our collection. All these measurements are in centimetres.



Just a heads up! These are the measurements of the clothes, not what you would measure on your body. It's generally easier to measure an item you already own that fits you well, rather than to measure on your body, as you'll find that measurements on yourself will be a bit smaller - this is because you'll need room to move in your clothes!

Measuring your clothes

The measurements in our size chart is measured on an item laying flat. For measurements like bust, waist and hip, the numbers you get when measuring flat are doubled to get the measurement around your body.


How to measure an existing item in your wardrobe that fits you well:

1. Lay it down flat, and stretch it out so that it is smooth.

2. Get a tape measurer and measure the key measure points for each specific item. They tend to be front length (from shoulder to hem), bust (across the chest under the arm), waist (at the narrowest point) and hip (about 20 cm below the waist).

3. Make a note of each measurement so you can compare with our size chart.


Remember that bust, waist and hip measurements will be double of what you measure when the item lays flat, as it goes around your body.

How to measure yourself

If you want to measure yourself to confirm what size you are, that can help give you confidence that you're choosing the best size for your body - although we recommend measuring on a similar item that fits you well.


Make sure you measure yourself in just your underwear, so you get accurate measurements. (Put the heating on if you have to...)


It’s best to wear an everyday bra, the kind you will be wearing with these clothes - we know our clothes are amazing, but no need to break out the fanciest Madonna corset for this measuring exercise. Use a measuring tape (a ruler just won't do, I'm afraid), and measure the following:

  • Bust - Measure around the fullest part of your bust and across your back
  • Waist - Keeping the tape measure taut, measure around your natural waist.
  • Hip - With your legs together, measure approximately 20cm down from your natural waist and measure around the lower part of your bottom.

Think about it as "biggest, smallest, biggest". You want to measure the biggest part of your chest, the smallest part of your waist and the biggest part of your hips!
