Now that is painful data…

Finding the perfect clothing size is a daunting task when shopping online.

When in doubt about the size and fit, customers resort to:

  • Abandoning their shopping cart.
  • Purchasing multiple sizes and returning those lacking the right fit.
  • Seeking additional guidance from customer service.

Each of these costs your business money and time. You also lose out on deepening your customer relationships and elevating your brand value.

  • A robust marketing strategy drives sales and growth, but building customer loyalty requires more. Providing personalized size recommendations ensures your customers find the perfect fit. It would be a shame to attract customers to your website, only to lose them because they couldn’t find the right size. By offering precise size recommendations, you enhance their shopping experience and keep them coming back.

Intuitive back-office 

Effortless Product Uploads

Our system automatically uploads your products from your Shopify store, streamlining the setup process and ensuring your inventory is always up to date.

When creating size charts for your products, be sure to return here and assign both a General (brand) size guide and a Product-specific size chart to each item.

To enable size recommendations on your storefront, ensure the recommendation algorithms are activated for every product. You can manage this in the last column of the dashboard.

 

To provide accurate results, SizeSense requires two types of size charts.

Step 1: Provide General (Brand) Size Guide

The General Brand Size Guide outlines the sizes you offer and the customer measurements that correspond to each size. For example, a Medium size might fit a customer with a bust of 96-102 cm, waist of 76-82 cm, and hips of 100-106 cm.

Single Brand? You only need one general size guide.

Multiple Brands? You’ll need a separate size guide for each brand.

SizeSense uses these types of size charts as a reference to understand your target customer’s measurements.

Step 2: Provide Product-Specific Size Charts

To provide personalized size recommendations, SizeSense needs specific garment measurements. These include bust, waist, and hip measurements for dresses, outerwear, and tops – and waist and hip measurements for skirts and pants. These are the mandatory measurements which SizeSense will need to provide your customers with accurate size recommendations.

You can create both types of size charts manually or easily import them!

Create or import your General Size Guide

Customize size names, add or remove sizes, define precise measurement ranges, and choose your preferred units (cm or inches). Assign the chart to a specific brand and save it with a clear, recognizable name.

Your general size chart should include measurement ranges. For example, for size Medium bust 96-102cm, waist 76-82cm, and hips 100-106cm.

Create or import your General Size Guide

Select the correct product category – Dresses, Tops, Bottoms, or Outerwear – so the right sizing algorithm is applied.

Choose your measurement units (cm or inches) and the correct brand/vendor.

If you’re filling out product size charts manually, you only need to measure one size of the garment – then enter the grading step, and our tool will automatically calculate the rest.

Fill in the required bust, waist, and hip measurements, with optional fields for biceps, length and inseam.

Define the intended fit by selecting an option from the dropdown for each area, and indicate whether the item has sleeves, straps, or is strapless. Add the fabric’s elasticity, then click Save to generate accurate size recommendations.

Effortless Customization 

You’ll be able to explore the various settings the app offers, giving you full control to configure and style it according to your brand’s look and feel. From colors and fonts to texts, everything can be customized to fit seamlessly into your store.

All This is Possible When You Use The Right Personalized Size Recommendation Tools

Many fashion brands focus heavily on attracting new customers through marketing and social media. They often overlook the importance of retaining those customers and creating a loyal base.

Instead of fostering long-term relationships, brands often prioritize short-term sales goals. Promotions, coupon codes, or a sense of urgency (usually: highlighting limited stock). On paper, these tactics sound good – they will spur impulse purchases, driven by what we call FOMO (fear of missing out). In reality, they often lead to a fashion brand’s biggest enemy:

Higher return rates and low customer loyalty.

The reason why is quite simple, really. These purchases were not driven by genuine need, interest, or cultivated brand awareness. They were driven by emotion. Once the initial excitement fades, customers experience buyer’s remorse. Soon, returns follow, as well as the risk of diminished customer satisfaction.
Additionally, brands may not invest in personalized shopping experiences, which are crucial for making customers feel valued and understood. When customers don’t feel a connection with a brand or don’t receive a tailored experience, they are less likely to return or remain loyal.

Brands that fail to address these aspects often struggle with inconsistent sales and lower customer retention, even if their products are high-quality and they have a strong online presence.

A robust marketing strategy drives sales and growth. The best Shopify apps are those that help you achieve this with ease.

Example of a Successful Solution for Decreasing Return Rates and Building Customer Loyalty

Let me provide an example to help you understand the concept better.

The truth is that…

Most fashion brands struggle with high return rates due to the 3 main reasons why clothing does not fit:

1. Clothes might be the same size, but their pattern is different!

Clothing size depends on both the fit of the clothing and the elasticity of the fabric. People rarely take this detail into consideration when they order clothes online. This intricate combination of factors is one of the main reasons why customers see themselves jumping between different sizes all the time.

2. Clothes might be the same size, but women’s bodies are different!

Even though clothes are labeled with the same size, women’s bodies vary widely in shape and proportions. This means that a size 8 dress might fit well on one woman but be too tight or loose on another due to differences in body shape and design cuts. Inconsistent sizing standards and fabric elasticity further complicate finding the right fit. As a result, customers often struggle to find clothing that suits their unique measurements, leading to frustration and higher return rates.

3. Clothes might be the same size, but the suppliers are different!

Even when clothes are labeled with the same size, the fit can vary significantly because different suppliers use their own sizing standards and patterns. Each brand may have its own interpretation of what a “size 10” should be, leading to inconsistencies in how clothes fit. This discrepancy makes it challenging for customers to find the right size, as they cannot rely on uniform measurements across different brands. Consequently, this variability often results in confusion and frustration for shoppers trying to find clothing that fits well.

When you consider these reasons, it becomes obvious that finding the right clothing size can be a complex and frustrating experience for customers due to inconsistencies in both body shapes and sizing standards across brands. This complexity underscores the need for more reliable sizing solutions to personalize shopping experience and reduce the likelihood of returns.

How can I choose the right size recommendation tool?

Don’t install a size recommendation tool on your website if it skips these crucial factors – you could be losing both customers and sales!

Through years of experience – from creating thousands of made-to-measure garments to helping customers find the right size online – we learned what it takes to get sizing right.

When making made-to-measure clothing, there’s no room for mistakes – especially for one of the most important days in our customers’ lives.

At SizeSense.ai, we don’t claim to be revolutionary. We’ve simply transformed our patternmaking and tailoring knowledge into code – knowledge that has existed for ages – and applied it to software.

So….Don’t install a size recommendation tool on your website if it skips these crucial factors – you could be losing both customers and sales!

❌ No 1:1 alignment between body and garment measurements

Most existing solutions rely on three flawed methods: analyzing past customer purchases, matching size guides across brands, or recommending sizes based on similar height and weight profiles. These approaches fail to account for each garment’s unique measurements, design, and manufacturing variations – often increasing return rates by misleading customers.

❌ Ignoring elasticity

A pear-shaped customer shopping for stretchy jeans may be told they won’t fit if fabric stretch isn’t considered – costing fashion brands a sale!

❌ Overlooking clothing design

A customer may wear one size in a loose, elastic dress but need a size or two up for a non-stretch shift dress – increasing the chance of returns.

❌ Ignoring body shape

Two people with the same height and weight can have vastly different proportions, affecting how a garment fits. Ignoring this leads to incorrect recommendations and higher return rates.

❌ Neglecting fit preference

Fit preferences vary – 17% of women prefer fitted clothing, 20% prefer a looser fit, and the rest opt for a regular fit. Ignoring this further increases return rates.

By addressing all these elements, SizeSense.ai ensures customers can confidently select the right size – reducing returns, increasing sales, and improving customer satisfaction.
