Taking Your Measurements
Accurate measurements are the foundation of a perfect fit. Follow this simple guide to take the three key measurements needed to find your size in our A-O system.
What You Need
Measuring Tape
A flexible fabric measuring tape. Avoid using metal or rigid tapes.
Mirror
A full-length mirror helps you check that the tape is level and positioned correctly.
A Helper (Optional)
Having someone help ensures more accurate measurements, especially for hard-to-reach areas.
Fitted Clothing
Wear form-fitting clothes or underwear. Avoid bulky layers that can add inches.
Before You Start
- Stand in a natural, relaxed posture—don't suck in your stomach or stand unnaturally straight
- Keep the measuring tape parallel to the floor for accurate horizontal measurements
- The tape should be snug but not tight—you should be able to slip a finger under it
- Measure directly against your skin or over thin, fitted clothing
- Take each measurement 2-3 times to ensure consistency
- Write down your measurements immediately—don't rely on memory
How to Measure
Bust
Measure around the fullest part of your chest. The tape should pass over the fullest part of your bust and straight across your back. Keep your arms relaxed at your sides and breathe normally.
Waist
Measure around the narrowest part of your torso, just above your belly button. This is typically where your body naturally bends when you lean to the side. Don't pull the tape too tight—it should rest comfortably against your skin.
Hips
Measure around the widest part of your bottom/hips. Stand with your feet together and ensure the tape is parallel to the floor all the way around. This measurement typically sits about 7-9 inches (18-23 cm) below your natural waist.
Pro Tips for Accuracy
💡 Don't Pull Too Tight
The tape should lay flat against your body without compressing your skin. If you pull too tight, you'll get measurements that are too small.
💡 Check the Back
Use a mirror to make sure the tape hasn't twisted or slipped up in the back. This is especially important for bust and hip measurements.
💡 Measure at the Same Time
Bodies fluctuate throughout the day. For consistency, measure yourself at the same time of day, preferably in the morning.
💡 Stand Naturally
Your posture should be relaxed and natural—the way you normally stand. Don't hold your breath or tense your muscles.
💡 Write It Down
Keep a record of your measurements with the date. This helps you track changes over time and know when to remeasure.
💡 When in Doubt, Size Up
If you're between measurements, it's usually easier to take in a garment than to let it out. Consider the fabric and style too.
Additional Measurements
For more advanced pattern adjustments, you may want to take these optional measurements. These aren't required for choosing your size, but can help with custom fitting.
Around your chest, above the bust, under the arms
From shoulder point to shoulder point across the back
Across your back from armpit to armpit
From shoulder point to wrist with arm slightly bent
From the base of your neck to your natural waist
From crotch to ankle along the inside of your leg
When to Re-Measure
Your body naturally changes over time, and that's completely normal. We recommend taking fresh measurements in these situations:
- Every 6 months as a routine check
- If your clothes are fitting differently than usual
- After significant weight changes (gain or loss)
- During or after pregnancy
- If you've started a new fitness routine that's changing your body composition
- Before starting a major sewing project
Remember: Your current measurements are the right measurements for you right now. There's no "ideal" size—only the size that helps you create garments that fit and feel great.
