Bodice Fitting Tools
Adjust your bodice pattern before cutting — shoulders first, then length, then back shape. Each tool gives you the exact amount and step-by-step instructions. Work through them in order for best results.
Shoulder Width Adjuster
FreeBroad or narrow shoulders? Calculate how much to add or remove at the shoulder point on both front and back pieces.
Swayback Adjuster
FreeEliminate the horizontal fold at center back waist. Works for bodices, skirts, and pants backs.
Bodice Length Adjuster
FreeCalculate front and back length adjustments independently. Handles cases where front and back differ.
Sleeve Fitting
FreeCheck bicep ease and calculate sleeve width and length adjustments for set-in and shirt sleeves.
Neckline Adjuster
FreeRaise, lower, widen, or narrow a neckline. Get CF/CB length changes and updated facing depth.
High Round Back
NewFix the horizontal fold across the upper back. Slash and spread the right amount at the right location.
Forward Shoulder
NewShoulder seam rolling to the front? Trim the front, add to the back — no change to shoulder length.
Full Upper Back
FreePulling across the upper back between the shoulder blades. Add width at CB seam or via slash-and-spread.
Sleeve Cap Ease Checker
NewMeasure sleeve cap and armhole circumference on your pattern. Check if the ease is right for your sleeve type.
Where to start
1. Shoulder Width — if your shoulders are broader or narrower than the pattern assumes
2. Bodice Length — if the waist seam doesn't hit your natural waist
3. Swayback — if there's a horizontal fold at the lower back waist
4. Sleeve Fitting — after the bodice is adjusted, check bicep ease and sleeve length
FBA/SBA adjustments interact differently — do them after shoulder width but before or after length.
Why the order matters
Bodice adjustments interact with each other. Changing the shoulder width shifts the armhole, which affects how the sleeve fits. Adding bodice length changes where the waist seam lands, which affects the side seam length and waist dart position.
The recommended sequence: shoulder width first (it's the highest adjustment and doesn't depend on anything else), then bodice length (now that the shoulder is set, you can measure the true length), then swayback (waist-level adjustment, done after length is finalized).
Full bust (FBA) and small bust (SBA) adjustments interact differently — they go after shoulder width but can be done before or after length, depending on whether the FBA changes your front length.
