I have a really easy set of Rowan pattern alterations for you today! I’ve had a lot of questions on how to alter this pattern for a longer torso, and the great news is it’s a very straightforward adjustment. So let’s get onto how to shorten or lengthen a bodysuit!
Click through for the steps!

The first step is to figure out how much you need to lengthen the torso by. I would also recommend tracing the pattern before making any adjustments to preserve the original pattern.
The pattern already includes lengthening/shortening lines, so once it is traced, simply cut along this line and spread the pattern by the desired amount. Place additional paper behind the pattern pieces to cover the gap, tape in place, and then true the side seams by trimming the excess paper away and ensuring your seamlines are still nice curves.
To shorten the torso you would follow the same method, but instead of spreading the pattern pieces apart, you would overlap them by the desired amount before taping and truing the seams.
Told you it was easy!

You can actually lengthen or shorten the tee variations in the exact same way, by slashing and spreading the pattern at the waistline – but I’d like to propose a simpler method for the tee. For tee variations, I would personally simply add onto the hemline. It’s faster and you can do it on the fly once your fabric is laid out, by simply cutting beyond the hemline by how much longer you need your tee. Easy peasy my dears!
