How to Make Sure You Always Get a Perfect Fit

How do you make sure you always get a perfect fit? Just follow some simple tips and use our intuitive sizing guide. Read on to learn more about how to pick a perfect-fitting dress from any of your favorite retailers.

Nothing's worse than investing in a new outfit only to realize that it doesn't fit. While it's easy to find out the size of a garment that you want to wear, every major fashion company uses a different sizing scheme to determine its sizes. Just because you usually wear a women's size 10 doesn't mean that every size 10 dress will fit you, and juggling clothing sizes can get old fast.

In this guide, we'll clear up all the confusion and help you determine your exact size in any major brand's apparel. Whether you want to make sure that your favorite Missguided, Boohoo, H&M, or Zara fashions always fit, we'll provide you with all the information you need to make accurate measurements and ensure that you'll never have to return a piece of women's clothing just because it doesn't quite fit once you get it home.

How Do You Determine Your Size?

Running a tape measure around your waist won't be enough if you want to know everything there is to know about your exact size. What's more, simply looking at a single women's dresses size chart won't be enough to make sure that you'll fit into every dress that catches your eye. Instead, you'll need to get to know the exact sizes of your body from top to bottom.

To determine your size with a size guide in the UK or any other country, you'll need to take three basic measurements:

1. Bust

To get an accurate idea of your bust size, you'll need to measure around the fullest part of your bust. If you don't measure around the fullest part, you might not get the information you need to accurately determine your size in a fit guide. Your bra size alone usually won't be enough to figure out the exact circumference of your bust, and you can't rely on the UK size of your favorite dress to give you an accurate idea of how you'll fit into other dresses.

2. Waist

Figuring out where your waist is can be one of the hardest parts of taking your body measurements. Your natural waistline isn't the spot where contemporary jeans or skirts usually ride; this spot is actually about an inch above your navel, and it's at the slimmest part of your waist. If you can feel your rib cage while you take measurements, you've put your tape measure too high on your abdomen.

3. Hip

For this measurement, circle a tape measure around the fullest part of your hips. It's generally easiest to find the perfect spot to take this measurement because you can simply feel for the area where your hip bones stick out the most.

4. Inseam

If you're planning to buy jeans or trousers, you should also measure your inseam. This inside leg measurement goes from your groin down your entire leg length.

How Do You Measure Yourself?

Measuring yourself can be somewhat tricky. However, there are a few simple tips you can use to make it easier to take the measurements you need for your women's size chart:

How to Take Bust Measurements

  • Stand in front of a mirror, and hold a soft tape measure in your hands.
  • You will get the most accurate measurements if you measure yourself braless or while you're wearing a non-padded bra.
  • Wrap the measuring tape around your back, and hold the two ends at the center of your chest.
  • Arrange the measuring tape until it wraps around the fullest part of your bust.
  • You may also need to arrange the way the tape measure lands on your back to get an accurate measurement.

How to Take Waist Measurements

  • Stand in front of a mirror, and remove your top.
  • Starting right above either hip bone, hold a soft tape measure in place while you wrap it around your back and across your stomach.
  • Make sure that the tape measure is riding straight, and note the number on the tape measure where the ends meet.

How to Take Hip Measurements

  • Stand in front of a mirror, and remove your pants or skirt.
  • Identify the widest part of your hip as the place where your hip bones bulge out the most.
  • Hold the end of the tape measure in place on top of your hip bulge.
  • Run your tape measure around your back, your other hip, and your stomach until the ends meet.

How to Take Inseam Measurements

  • You may need someone's assistance to take accurate inseam measurements.
  • Hold the end of a soft tape measure against your groin, and allow the rest of the tape measure to fall to the floor.
  • From the top of the inside leg down, hold the tape measure against your leg until you reach the bottom of your bare feet.
  • It's usually necessary to bend over to measure your inseam, but doing so can bend your knee, which alters your measurements.
  • Ask someone to help you measure your inseam if you aren't sure you'll get accurate measurements.

Can You Have Someone Else Measure You?

Taking your measurements can sometimes be too challenging to do on your own. It's understandable to want help with this process, and there are a variety of ways you can get a helper to assist you with your measurements.

For instance, you could ask a friend or family member to hold the tape measure in place while you wrap it around yourself, or you could have them do the wrapping while you do the holding. Having someone help you is especially useful when you're taking inseam measurements; hold the end of the tape measure by your groin while your friend holds it to the bottom of your foot.

PRO TIP: Some department stores will take your measurements for you. Many stores take your bust measurements for bra fittings, and they may also be willing to measure the rest of your body if you ask politely.

Understanding Sizing Guides for Top Retailers

Every major retailer has a size guide that it uses to determine its apparel sizes.

Pros and Cons of Using Size Guide Tools

There's no doubt that size guide tools are incredibly helpful. However, you should know that these tools have limitations before you proceed:

Pros

  • Helps you find out if a dress or another garment will fit before you try it on.
  • Makes online purchases easier.
  • Reduces the number of times you'll have to go to the post office to return items that don't fit.
  • Are more accurate than simple size numbers if you want to make sure that a garment will fit.

Cons

  • Doesn't tell you everything you know about how a garment will fit.
  • Not all apparel companies provide size guides that are easy to find and use.

Tips for Making Sure You Never Get a Bad Fit

If you keep picking out clothes that don't fit no matter how hard you try, keep these simple tips in mind to end your bad habit once and for all:

1. Don't Buy on Impulse

We've all been there: The fitting room was too far away, there weren't any stalls open, or we were in a hurry. However, there's no excuse for buying a dress or another piece of apparel without knowing for sure that it will fit.

Don't let exclusive offers and the rush of the day get to you; always make sure that a garment fits before you bring it home. This principle applies to online purchases as well; don't get carried away just because that dress looks perfect on your laptop or smartphone screen.

2. Keep Your Measurements in Mind

Just because you've always fit into a size six before doesn't mean that size six dress you've fallen in love with will fit you when you get home. Instead of relying on complicated size conversions and the varying clothes sizes of different companies, keep your measurements on your smartphone in the form of a note. If you're ever concerned that an item you want to buy won't fit, ask to see the company's size chart, and plug in your measurements to make sure the garment will fit before you put it in your physical or virtual shopping bag.

3. Don't Cut off the Tag

Even if you're completely sure that your new fashion will fit, don't make it harder for yourself to return the item if it doesn't work out. Some retailers won't take a garment back if you cut off the tag, and make sure to keep your receipt.
