The pattern calls for you to sew the tucks all the way to the bottom of the garment, but she modified it to only sew past the bust to allow for a little bumpage. I did the same since there is officially bumpage here. Students started commenting, so I must be showing.
I'm excited to try sewing more clothes for "maternity" wear. I'd like to use patterns I already have but am not 100% sure how to go about modifying those patterns. I'll keep you posted on my progress, or frustrations.
