Did you know that most sewing patterns are drafted for a B or C cup size bust (with a few exceptions like Cashmerette Patterns which go up to an H!) , but the average woman is a DD? But don’t worry – it’s possible to adjust any sewing pattern to make the bust size bigger, in a few steps, using a Full Bust Adjustment.
This tutorial is specifically for dresses or tops that don’t already have a dart in them, so it adds the space you need as well as a new dart. It works for patterns like the Sewaholic Belcarra Blouse, the Megan Nielsen Eucalypt top/dress, or the Grainline Scout.
3. Mark three lines coming out of the apex
The first one should go from the apex up to the armhole, about 1/3 of the way up. The second should go vertically straight down the pattern from the apex. And the third goes at a gentle angle toward the side seam (you can just judge the angle by eye).
7. And here we are!
The adjusted piece. Sew up the dart before you sew up the rest of the dress, and the Tank Dress will suit you oh so much better!
