What Size Are You?

Click left arrow to hear the audio

Asking “What size are you?” of someone you don’t know really well can be very uncomfortable. I would be extremely unlikely to tell anyone my clothing size unless I knew them intimately, and even then I’m not sure that I’d be willing to part with what (in my opinion) is considered “classified information”. That being said, I will be the first one to admit that I’ve been given many clothing items over the years that have never seen the light of day because they were the wrong size — usually too small. Even though I was flattered that the gift giver thought I appeared thinner than I really was, it would have made life easier just to give them the necessary information. (No wonder gift cards are so popular these days.)

Clothing that is too large can usually be altered and taken in (especially when the person is handy with a sewing machine), but items that are too small can only be returned to the store for a larger sized item, re-gifted to a trimmer (usually younger) version of the person, or stored in the closet for future wear for the time that they “will lose the extra weight". (We won’t even go into clothing colors as that is another potential sore point that deserves a separate article!)

So, how can you find out what size someone is? Well, the obvious thing to do would be to ask them! (Good luck with that.) It’s not easy to buy clothes for someone else unless they tell you and even then, different brands size their clothes differently, so what is a 10 in one store will actually be a 12 in another. Most women won’t want to tell you what size they are. Guys are easier in that respect, but a lot of them don’t know!

How to find out if they won’t tell you

How sneaky can you be? Don’t guess at sizes — that’s a sure way to have a gift returned.

Taking proper measurements — congratulations!

woman saying ok You’re about to measure someone (maybe yourself) to ensure the clothes you buy will fit nicely! Use a cloth or flexible measuring tape (not the one you use to measure wood and drywall) so the measurements are as accurate as possible. For best results, have the person wear their undergarments. If that’s not possible, then tight fitting clothes might be OK. If you’re really comfortable with the person, the “Lady Godiva” look also works (however, note that a properly fitting bra will give you a different bust measurement than just letting "the girls” hang loose)!

Bust or chest:

Making sure the measuring tape is parallel to the ground and not too tight, measure under the arms and around the fullest part of the bust/chest. Measuring for a bra is a little more complicated. (See our article on "How to Measure "The Girls".)

Have the person bend to one side. The “waist crease” created will be the location of the natural waist which is usually the smallest part of the waistline. Measure around at that point.

Hips:

Measure around the widest part of their hips and rear while they stand with their feet together.

Inseam:

Measure from the crotch to the ankle on the inner leg — this can be done without shoes. For dress pants or pants to be worn with heels, wear the shoes and measure from the crotch to the bottom of the shoe. Remember, you can always hem pants if they are too long, but you can’t add length if there is not enough material, so if in doubt, longer is better.

silhoutte of man Neck:

This is a common measurement for men’s shirts. With a finger underneath the tape to make sure the collar is not too tight, measure around the fullest part of the neck “eyeballing” where a shirt collar would normally sit. Round up this measurement to the nearest ½ size.

Sleeve length:

Also mainly used in sizing men’s dress shirts, measure this length by having the person bend their arm and place it on their hip. Starting at the center of their back, measure across their shoulder, down the elbow and then to the wrist. Round up to the nearest whole number (shirt sleeve lengths are always in whole numbers and range from 32 to 39 inches).

When all else fails

This method may not be completely accurate, but it works pretty well on items that have a little “give” in the fabric. Carry a small tape measure with you — it will come in handy when you have clothing that doesn’t have a size label.

Tops/sweaters/jackets: Lay the item on a flat surface. If there are buttons, button them all the way down. Measure the chest/bust area just under the armpits (see pic) and double the measurement. For example, if the measurement is 18”, double that and you have 36”. If you know the item you’re measuring is tight on the person, add a half inch. Also measure the bottom of the item to make sure it will fit over the hip area (and double it).

Skirts/pants: Lay the item on a flat surface and make sure all zippers or buttons are closed. Measure the waist band and also around the hips and make sure you double the measurement (2D people only exist on paper). The hip area should also be measured — this will be about 8 inches below the waistband. Measure the inseam on the pants (the length of the inner leg from the crotch seam to the bottom of the pants). Remember to add some extra length (about ½ inch) if you want to buy something that will be worn with heels.

These measurements should be enough to get a basic idea of sizes. You can then compare sizes with a sizing chart of an online retailer to get a good idea if the item you want to purchase will fit or not. Take a measuring tape with you to the store. I usually do, especially if I’m somewhere new.

Different fits

Some garments are labelled with “Relaxed fit” or “Comfort fit”. This simply means that even though the size may be the same as the other item of clothing, the garment has a bit more “ease” (room) than the other more form-fitting style.

When in doubt, don’t be afraid to ask a salesperson. They should be able to help as long as you have the measurements.
