What Is a Size Medium in Numbers for Dress

Knowing how to interpret sizes is an invaluable skill in the clothing industry, where I work in supply chain procurement.

Explaining Women Clothing Sizes

I work in the clothing industry, so I know that finding the right size is often tricky. Sizing varies widely over time, clothes are often tagged incorrectly, and wearers' personal sizing preference (baggy vs. fitted) can all lead to mistakes. You can buy the perfect size for a person's body and it still might not be the "right" fit.

Unfortunately, to make matters worse, there is no industry sizing standard. Every brand uses its own random measurements to determine its size tags, and this means that a person who fits a size M in one brand may need a L in another. You simply can't know for sure if something is going to fit you unless you try it on.

Rather than looking at size tags, looking at measurements is the best way to proceed. Here are some raw sizing basics that might help you get the right size and fit. In this article, we'll get into what all of those letters and numbers translate to in terms of size.

How to find the right size when shopping online.

How to Measure to Find Your Size

Use a soft, flexible tape measure to take your measurements.
Make sure to lay it flat and snug (but not tight) and keep it parallel to the floor.

Measure against skin rather than over clothes.
Don't hold your breath or suck yourself in, as this defeats the purpose! :)

How to measure your chest:

Place the tape measure around the widest part of your chest, under your arms. It helps if you hold both arms up and have a friend take the measurement.

How to measure your waist:

Place the tape measure at the smallest part of your waist, just above your belly button. Try to keep the tape measure parallel to the ground.

How to measure your hips:

Measure the widest part of your hips, usually just below the hipbones. Keep the tape measure flat and even.

What if I don't have a tape measure?

Don't worry—just use a piece of yarn or string or even a shoelace, then measure that with a ruler or yardstick.

Should I measure my body or my clothes?

Measure your body, not your clothes. If you were going to copy and sew a new garment, you would want to measure the clothing itself, but if you're just hoping to find the right-size garment, then measure your body.

Kristin on January 25, 2016:

Hi, I came across women's pants that have "xUU" (such as 10 xuu) and have no idea what it means. Can you explain??

TurtleDog (author) on December 15, 2010:

Very well said Amy! A lot of really good points on the odd variance you can sometimes get between stated size and actual size. Even things less thought of like laboratory (latex) gloves fit differently. In that case it usually has to do with the country of origin (and the size of their population :-)

Thanks for the comment! Really appreciate it.

Very interesting topic. Since I do most of my shopping online, I check the size charts (European clothing is generally less generous than American sizes) and always read reviews before making a purchase. Certain manufacturers apparently calibrate sizing differently (Pilco jeans sold at Anthropologie are notorious for "tight through the thighs no matter the size and generally, the more expensive, the more generous the material). I often wonder if the motivation of expensive lines is more promotional, flattering the consumer to increase sales. The type of material (stretch factor) can have a bearing. The cut of a dress can create a design that is more or less forgiving depending on body type. Shoes can be tricky, and I've found reviews from buyers are the best indicator regarding how true to fit a product runs. Thank you for this informative and well done write on an interesting subject.

Hi! Thanks for the great question I'd suggest double checking my answer with the store or site you are looking to buy from but I do believe that women's full in most Halloween costumes range from 16-18 and even a broader range of 14-18 depending on where you are shopping. Best bet is to double check this since Halloween costumes vary in styles and sizes enough that it can be tough to pin down an exact number.

Thanks again for reading!
