I got a question about this, and figured it’s good info to post, so here goes:
This is Pullip wearing one of the Isul Basics patterns. Groove often models their outfit packs on both Pullip and Isul, so the two dolls are known to be able to share clothes, but here’s the info you need to know about how Pullip (type 4) wears the patterns specifically:
Pants are short. Not by a lot, by about .5cm. They also do not fit snugly at the waist. They fit perfectly through the hips and legs, though. If you want to use the Isul pattern to fit Pullip better, extend the length of the pants by .5cm and do not use the waist band. Instead, just hem the top of the pants.
Tops fit, but are not fitted like they are on Isul. To use these patterns on Pullip, instead of using a 1/8″ seam allowance on the pattern pieces, use a 1/4″ seam allowance and trim the seams back after you sew.
This will work on both the Basic and Fancy pattern pack outfit pieces. Eventually I’ll probably put together a basics set that perfectly fits Pullip, but I wouldn’t expect it for a few more months. Until then, this works in a pinch :)
