My Fitting Profile
Enter your measurements once. We'll calculate every adjustment you need — which tools to use, how much to adjust, and in what order. Your profile saves in your browser and auto-populates the calculators.
Core measurements
These four determine your size, cup, and whether you need bust adjustments.
Under your arms, above your bust — the ribcage measurement
At the fullest point of your bust
At your narrowest point — bend sideways to find it
At the fullest point — usually 7–9" below the waist
Additional measurements (optional — more data = better recommendations)
Base of neck to natural waist, down the center back
Across the back, shoulder point to shoulder point
Total height, no shoes
Around the fullest part of your upper arm
Shoulder point to wrist bone
Crotch to ankle bone, inside leg
Sit on a hard chair. Measure waist to chair surface.
How to measure
Wear the undergarments you plan to sew over — typically a well-fitting, non-padded bra. Stand straight, breathe normally, and don't pull the tape tight. Have someone help if possible — it's hard to measure your own back accurately.
High bust: Wrap the tape under your arms and across the top of your bust, above the fullest point. This measures your ribcage and is used to determine your pattern size.
Full bust: At the fullest point of your bust. The difference between high bust and full bust determines your cup size and whether you need an FBA or SBA.
Waist:At your natural waist — the narrowest point of your torso. Bend sideways to find it; it's where the crease forms.
Hip: At the fullest point of your hips and seat, usually 7–9 inches below your natural waist. Keep the tape level all the way around.
What the recommendations mean
The recommendations are based on comparing your measurements to standard pattern assumptions (B cup, 5'5"–5'6" height, proportional waist-to-hip ratio). They tell you which adjustments to make before cutting to get a better starting fit.
High priority means the adjustment is large enough to significantly affect fit — don't skip it. Medium will improve fit but isn't critical. Low is fine-tuning — address after the major adjustments.
These are starting points, not final answers. Always make a muslin (test garment) to verify the fit before cutting your fashion fabric.
