Shopping online for every day clothing can be challenging experience. Shopping for Halloween Costumes presents similar challenges. Finding the right look can be exhaustive in itself, too. We hope we can help you make the process a little easier. We're writing this guide in order to help shoppers find apparel, like costumes, with a better fit in mind.

This journey starts by taking a few simple measurements.

Bodies change all the time. So you'll need to find your current measurements by using a tape measure. You may need to have someone help you. Make sure the measurements are true and current.

Here's quick guide to get those measurements:
- For women, find your bust, waist and hip measurements in inches (and/or centimeters). Make sure to use the fullest part of each area to get the right measurement, except when measuring your waist. Starting at one point, wrap the tape all the way around each section of your body and pull it snug (but not too snug). You may need to stand in front of a mirror to find those fuller parts. Once you've wrapped the tape around, end at the same point you've started. Write those numbers down.

- For men, find your chest, waist and inseam measurements (and/or centimeters). Make sure to use the fullest part of each area to get the right measurement, except when measuring your inseam. Starting at one point, wrap the tape all the way around each section of your body and pull it snug (but not too snug). Once you've wrapped the tape around, end at the same point you've started. For the inseam, measure from the top inside of your leg to your your foot. You may go even further by measuring your neck and arm length for more fitted costumes. Write those numbers down.

Now that you know your measurements, you can shop online with greater ease.

Another very important point to keep in mind is to find out if there are variations to the size charts by contacting the seller directly. National brands, for the most part, do thorough research and provide size charts that apply to most people. You may have noticed that a women's size M in today's size chart is fuller than it used to be. In some cases, some manufacturers take liberties of having a broader range in their measurements for a size M (medium), for example. So, there's limited consistency in size charts.

Some small manufacturers usually use standard size charts to a point, but since they are the ones running the machines, and there are tens of thousands of clothing manufacturers worldwide, sizes vary widely. They also vary by country.

We suggest not to marry a size. Use sizes simply as guides to get you where you want to go. It's much better to go by the actual measurements in inches or centimeters, anyway.

If clothing isn't manufactured in the US and is meant for European customers, for example, don't just buy it because it reads your size! You'll need to gather a whole new set of measurements if you decide to go global. You may find that measuring yourself using the metric system is a headache, but it's actually a little more detailed in increments than using inches.

Save yourself some time and find both measurements at the same time. Make a Word file of it, put it in your PDA or whatever and keep track. You'll see that, in time, those numbers may change.

Now you are totally ready to shop for clothing like a pro!

You'll open yourself up to costumes and clothing from all over the world and not just clothing made with the US consumer in mind.

The shopping experience is a two-way street. Communication from buyers and sellers is key and its essential in finding the right look and in maximizing the experience.

As a customer, you deserve to know what size M, L or OS means if it's listed as such in the listings. Locate a size chart in the listings or in the faqs of online sites or from sellers' stores, if it's provided. Contact sellers with questions if the information isn't available.

Buying costumes, in particular, can be a simple enough experience with measurements in hand.

If you require specialty products, such as Plus Size or Big/Tall costumes, find out if your favorite sellers have these categories or run searches in their listings for keywords such as "plus size" or "tall". Other keywords like "one size" are popular since items such as hats are made with the general sizes in mind.

Doing a little homework ahead of time will save you hours of shopping time online and eliminate a lot of guesswork.

If, for some reason, things don't work out quite as well as you had hoped, contact your seller. Let them know how they can help you. Some sellers have great exchange policies with the objective of getting the best fit possible for you. After all, they're there to help you find that great looking best fitting costume just in time for Halloween or any time of year!
