Tired of returning clothes that don’t fit? Learn exactly how to pick the right plus size when shopping online with our expert measuring tips and fabric guides.

Welcome to The Curvy Cart! If you’re a plus-size shopper, you already know the emotional rollercoaster of online shopping. You find a gorgeous dress, add it to your cart, wait days for it to arrive, and then… it doesn’t zip. Or worse, it’s awkwardly baggy in all the wrong places.

Let’s be honest: your body is never the problem—inconsistent sizing is.

Every brand cuts their clothing differently, which means your “usual size” doesn’t really exist online. But don’t worry! With a few simple tricks, you can dramatically increase your online shopping success rate. Here is your ultimate guide to picking the perfect plus size when shopping online.

1. Ditch Your “Usual Size” and Grab a Measuring Tape

The biggest mistake you can make when shopping for plus-size clothing online is assuming that because you are a size 18 at one store, you are a size 18 everywhere else. Vanity sizing is incredibly common, and European sizing differs wildly from US or UK sizing.

Your best friend is a soft, flexible measuring tape. Here is what you need to measure (keep it snug, but not tight!):

Pro Tip: Take your measurements every 3 to 6 months, as our beautiful curvy bodies naturally fluctuate! Write them down in your phone’s notes app so you always have them handy.

2. Decode the Brand’s Specific Size Chart

Now that you have your measurements in inches or centimeters, ignore the big bold “2X” or “Size 22” on the product page and immediately scroll down to the Size Guide.

Match your personal measurements to the brand’s chart. If your measurements fall between two sizes:

If your top half is a different size than your bottom half (very common for pear or apple shapes!), always fit the widest part of your body. It is much easier to take in a waist at the tailor than to magically add fabric to tight hips!

3. Pay Close Attention to the Fabric Blend

Fabric composition will make or break the fit of a plus-size garment. Always check the “Materials” or “Fabric and Care” section of the product description.

4. Let the Reviews Be Your Guide

Never underestimate the power of a comment section! Reading reviews from other plus-size women is like having a fitting room bestie.

5. Always Check the Return Policy First

Even with perfect measurements, sometimes a garment just doesn’t vibe with your personal style once you put it on. Before you hit “checkout,” always verify the store’s return policy.

Shopping with brands that offer hassle-free returns takes the anxiety completely out of the online shopping experience.
