Trillium is the new name for the pattern previously known as Washi; you can read about the name change here. It's the same fantastic pattern, just updated and improved!
With the update to this pattern, we expanded the size range and added an additional C/D cup bodice pattern piece for fuller busts (see all size charts here). We also added metric numbers to all of the charts and instructions, which now come in a handy stapled booklet rather than an instruction sheet.
As always, the pattern pieces are printed on our high-quality pattern paper that is easier to trace, fold, and store than traditional pattern tissue.
