Full Twist Top Bust Adjustment Tutorial:
This free full twist top bust adjustment tutorial for a twist top will guide you through an FBA. The RP ladies’ XXS to 5XL sewing patterns are designed to fit a sewing C cup bust, which is a B cup in most ready to wear bras. If your bust is bigger or smaller than this, you may require an FBA.
After measuring your bust accurately and determining the best size to whip up, follow this tutorial for knit patterns for the best fit.
For a perfect fit, always make up a muslin first. Make the necessary adjustments to which ever pattern piece needs them. Try it on, check the fit is good for you. Then only cut into the fabric you want to use for your final garment once you know you’re fully happy with your muslin.
