How do you choose the right size when shopping online?
Choosing the right size when shopping online can be a challenge because you can’t physically try clothes on. Different brands often use different sizing systems, so a size 38 from one brand may fit differently than from another. By measuring yourself correctly and reading size charts carefully, you significantly increase your chances of a perfect fit.
Why is choosing the right size so tricky when shopping online?
Without a fitting room, shopping for clothes online becomes a gamble. You can’t feel the fabric, you can’t test the fit, and you have to rely on product photos and descriptions. This often leads to disappointment when the package arrives.
The biggest problem is that brands use different sizing systems. A Dutch size 38 may be labeled a 42 by an Italian brand, while American sizes work completely differently. Even within Europe, there are differences between countries and brands. That makes choosing the right size without trying it on even more complex.
That’s why many shoppers order several sizes at once to try on at home. This means extra shipping costs, more packaging, and the hassle of returns. The frustration of sending back clothes that don’t fit is a reason for many people to avoid shopping online altogether.
How do you measure yourself for the perfect fit?
Measuring correctly is the foundation for finding your right size. All you need is a flexible tape measure and perhaps someone to help with hard-to-reach spots. Always measure over your underwear for the most accurate results.
For your bust, measure at the fullest part of your chest, preferably while wearing a bra. Keep the tape measure horizontal and make sure it isn’t too tight. Measure your waist at the narrowest point of your midsection, usually just above your belly button. For your hips, find the widest point, about 20 centimeters below your waist.
Key tips for accurate measuring:
- Measure in the morning for the most consistent results
- Stand up straight and relaxed while measuring
- Breathe normally; don’t hold your breath
- Write down all measurements in centimeters
- Measure twice to be sure
Common mistakes include pulling the tape measure too tight or measuring over thick clothing. People also often forget that for pants, you need to know your inseam length too.
What are the differences between Dutch, European, and international sizes?
Sizing systems vary considerably around the world. Dutch sizes (36, 38, 40) are used in many European countries, but not always in the same way. Italian sizes, for example, run two sizes larger, so a Dutch 38 is a 42 there.
American sizes use a completely different system. They use sizes such as 4, 6, and 8, with a US size 6 roughly equivalent to a Dutch 36. UK sizes fall somewhere in between, with UK size 10 equivalent to NL 38.
| Dutch size | European size | UK size | US size | Italian size |
|---|---|---|---|---|
| 36 (S) | 36 | 8 | 4 | 40 |
| 38 (M) | 38 | 10 | 6 | 42 |
| 40 (L) | 40 | 12 | 8 | 44 |
| 42 (XL) | 42 | 14 | 10 | 46 |
Please note: this conversion chart is a guideline. Brands may deviate from this standard; fast fashion chains in particular often use their own sizing systems.
How do you read a size chart, and what should you look out for?
A good size chart always lists body measurements in centimeters, not garment measurements. This distinction matters because clothing needs room for movement. Look up your measured bust, waist, and hips in the chart.
When interpreting size charts, keep these points in mind:
- Look at all three measurements (bust, waist, hips), not just one
- Check whether the measurements are body or garment measurements
- Pay attention to additional fit information (slim fit, regular, loose)
- Check whether length information is included
If you’re between two sizes, choose the larger size for stiff fabrics and the smaller one for stretchy materials. For outerwear such as blazers, it’s wise to go for the larger size so you can comfortably wear something underneath.
Which online tools help you find your size?
Modern technology is making it easier and easier to choose your size online. Virtual fitting rooms use your webcam to scan your body and recommend the right size. These tools are becoming more and more accurate, but they do require you to wear close-fitting clothing while scanning.
Size advisors are questionnaires that help you determine the right size. They ask about your usual size at well-known brands, your height, weight, and fit preferences. Based on this information and data from previous customers, they give you a size recommendation.
AI-powered tools analyze return data and reviews to recognize patterns. They can predict whether a garment runs large or small and offer personalized advice. This technology keeps getting smarter but isn’t perfect yet. So always combine several sources of information for the best result.
What do you do if you’re between two sizes?
Being between two sizes is very common, especially since bodies rarely fit perfectly into standard sizes. The choice depends on several factors. For dresses and tops, focus mainly on your bust measurement; for pants and skirts, your hip measurement is key.
The type of fabric plays an important role in your choice. Materials with elastane or modal stretch with you and offer more flexibility. With these fabrics, you can often choose the smaller size. Stiff fabrics such as cotton without stretch call for the larger size for freedom of movement.
Personal preference matters too. Do you love a close fit, or do you prefer something a little looser? For workwear, we recommend choosing the larger size so you look professional and feel comfortable. For casual wear, you can go more by feel.
How important are reviews and other customers’ experiences?
Customer reviews are worth their weight in gold when shopping online. They give you insight into the actual fit that product photos can’t provide. Reviews about sizing tell you whether an item runs large or small compared to the size chart.
When reading reviews, pay attention to these aspects:
- Look for reviewers with your body type
- Filter by your own size for relevant experiences
- Watch for comments about shrinkage after washing
- Look at photos customers have posted
- Read several reviews for a complete picture
Read with a critical eye. One negative review about sizing isn’t necessarily representative. Look for patterns in the feedback. If several people say an item runs small, that’s probably accurate information.
