Shopping for clothing online is becoming increasingly common, especially during the summer months: sales, new collections, and the desire to dress up for vacations and events drive millions of users to search for new looks online. But how do you figure out your size online? It’s common to receive items that are too tight, too loose, or poorly proportioned compared to expectations.
The real problem is the lack of definitive sizing standards, combined with the difficulty of predicting the fit without physically trying on the garment.
Summer: A Boom in Online Shopping and the Problem of Returns
During the summer, online shopping skyrockets. But along with it, the number of returns also rises: estimates for 2025 indicate that between 70% and 80% of returns in the fashion industry are caused by incorrect sizes or poor fit.
Most common reasons:
- Sizes that don’t match the size chart
- Fit different from what’s shown in the catalog
- Items unsuitable for the customer’s body shape
Without fitting rooms or the ability to try items on, making a choice becomes risky and frustrating, especially for categories like denim, blazers, or swimwear.
Why is the sizing system so confusing?
1. Country-specific standards and unclear conversions
Brands use different size charts (Italy, UK, USA), and automatic conversions are often misleading: an Italian size 42 might be a French size 38 or a UK size 8
2. Fit information isn’t always provided
Styles like slim fit, oversized, or regular are often not clearly indicated, making choosing a size a shot in the dark.
3. Generic size charts and imprecise information
Many websites feature generic size guides that aren’t specific to each garment. As a result, they use an average that represents almost no one.
4. Body measurements vs. garment measurements
Some platforms list ideal body measurements, while others list the actual garment dimensions. The difference is subtle but crucial.
5. Inclusive sizing
People with curvy, athletic, or petite body types often have to order multiple sizes and return many items
Emotional risks: shopping becomes stressful
Constant uncertainty creates not only logistical hassles but also a sense of frustration. Shopping should be an enjoyable, experiential activity. But the risk of making a mistake with every order significantly reduces that enjoyment and increases cart abandonment.
Many users avoid buying certain items online altogether—such as denim, blazers, or swimwear—preferring accessories or items that are easy to get right without trying them on.
Optimized tips for finding your size online
- Measure your body accurately
- Use a soft measuring tape to measure your bodice, waist, sides, shoulders, and length of the legs before finalizing your purchase.
- Always consult the product-specific size guide
- The size guide for each item is gold: compare it with your measurements in cm to minimize errors.
- Read user reviews
- Reviews often provide an honest assessment of how the garments fit—take a look before confirming your purchase.
- Compare items you already own
- Measure the items in your closet that fit well to compare them with the size charts on the website.
- Consider the fabric and style
- Stretch and jersey fabrics tend to fit more true to size, while stiff or tailored denim requires more careful consideration.
- Know your body type
- It’s easier to predict the fit if you know your body and which cuts flatter your figure.
Technological tools: from virtual fitting to 3D scanners
Virtual fitting room
Advanced technologies allow you to upload images and see how a garment fits on a personalized avatar, making it easier to predict the fit.
Amazon, for example, recently launched an AI-powered Fit Insights tool that analyzes reviews, feedback, and data to recommend more accurate sizes and reduce returns by 5–40%.
These tools are radically changing the shopping experience and the way people choose their size.
