Laura Tegg's freely available Weebee doll pattern. Laura has several clothing patterns that are free for this adorable doll, and some paid patterns.
This is a knit outfit that I designed for my Weebee's. My dolls are small; they are worked with sportweight yarn and a size C (2.5mm) crochet hook, so they turn out about 7.5 inches tall. My knitting gauge for this outfit is 6sts/inch in stockinette. Here is the pattern, with some gauge recommendations if your doll is larger than mine:
Knit Outfit for Weebee
I have NOT tested the pattern on any doll other than my own, so if you make this for your doll, definitely try to check the fit as you go. This is not as easy with knit as crochet, so you may find yourself making more than one garment to get the fit right.
I would suggest starting with the dress and/or the cap. These are pretty simple outfits, so adding a few stitches would not be difficult, to get the fit you want.
Have a great day, and enjoy the crochet!
