Shopping for work clothes online is convenient, but finding the right fit isn’t always easy. A size 6 in one brand may fit completely differently from a size 6 in another, especially when shopping for tailored trousers, blazers, and dresses.
One of the simplest ways to shop more intentionally is to know your measurements before making a purchase.
As a Workwear Strategist, I believe a polished wardrobe starts with understanding what works for your body, lifestyle, and personal style.
Here’s how to measure yourself before your next online workwear purchase.
What You’ll Need
All you need is a flexible measuring tape, a mirror, and your phone to record your measurements.
If you don’t have a measuring tape, I’ve linked an affordable option to help you get started.

For the most accurate results, wear fitted clothing or undergarments, stand naturally, and keep the tape comfortably snug without pulling too tightly.
1. How to Measure Your Bust
Wrap the measuring tape around the fullest part of your bust, keeping it level across your back.
Workwear Tip: Your bust measurement is especially important when shopping for structured blazers, button-down shirts, and fitted dresses. Pay attention to whether the garment is designed for a tailored or relaxed fit.

2. How to Measure Your Waist
Locate your natural waist, typically the narrowest part of your torso, and wrap the measuring tape around it without holding in your stomach.
Workwear Tip: Consider where your trousers are designed to sit. High-waisted and mid-rise styles may require different measurements and fit considerations.

3. How to Measure Your Hips
Stand with your feet together and measure around the fullest part of your hips and seat, keeping the tape level.
Workwear Tip: When shopping for tailored trousers or skirts, prioritize a comfortable fit through your hips. Depending on the garment’s construction, having the waist altered may be a better option than purchasing a size that’s too small.

4. How to Measure Your Inseam
Measure from the top of your inner leg to your preferred trouser hem. You can also measure the inside seam of a pair of trousers you already own that fits well.
Workwear Tip: Your ideal inseam may vary depending on whether you’re wearing flats or heels, particularly with wide-leg trousers.

How to Use Your Measurements When Shopping Online
Once you’ve recorded your measurements, compare them with the retailer’s size chart before selecting your size.
A few things to consider:
- Fabric: Does the garment have stretch, or is it made from a structured material?
- Fit: Is it tailored, relaxed, or intentionally oversized?
- Length: Will the proportions work for your height and preferred shoes?
- Reviews: Are customers consistently mentioning sizing or fit issues?
Also, check whether the size chart lists body measurements or actual garment measurements. They aren’t always the same.
Your Measurements Are a Starting Point, Not a Perfect Formula
Knowing your measurements won’t guarantee a perfect fit every time, but it can help you make more informed purchases.
Your measurements can also provide useful insight into your body proportions, help you explore silhouettes that complement your preferences, and make conversations with a tailor more productive.
Remember, measurements don’t tell the entire story. Fabric, garment construction, and personal fit preferences all influence how clothing looks and feels.
The goal isn’t to fit into a particular body type or clothing size. It’s to understand your proportions and choose pieces that make you feel comfortable, confident, and polished.
Better Fit, More Intentional Style
Building a polished work wardrobe isn’t about constantly buying more. It’s about making thoughtful decisions and choosing pieces that work together.
Keep your measurements saved on your phone, reference them when shopping, and remember that the right fit matters more than the number on the label.
