If you have a good eye for patterns and know how to alter them, you can make enough changes to commercial patterns to make them unique. Many commercial patterns are easy to alter - once that's done you have a unique pattern and no-one can accuse you of theft or misuse. If you take a look at several patterns (for dolls or humans), you will see that they are all based on a few basic shapes which are then made into different pieces of clothing by adding darts, different sleeves, different lengths, etc. Also, some of the people who provide free patterns on the Internet may be willing to allow you to use their patterns if you simply ask for their permission. It might mean you paying them a small user's fee or royalties, or they might even allow you to use the patterns for free.

I'd buy the Bratz doll clothes, take them apart and compare them to the Barbie patterns. That should tell you if the doll clothes patterns are interchangeable.

I've sewn doll clothes for years(over 40),for my DD then GD'S and now GGD's.And the other poster are correct,get the doll first.I have a soon to be 3 year old GGD,and she loves the soft dolls i make,(think rag dolls).She loves to drag them around with her for play and for bedtime.I make her the dolls and the clothes.She isn't to the stage yet where she just wants to change their clothes all the time,she just likes playing with them,talking to them etc. I've made her dolls,bunnies,bears etc,and different sizes in all of them.Then she just took over some of those sort of dolls that i keep around the house for when the kids come over. If she lives close by,take your cues from her!!My almost 3 year oldGGD plays with Barbies,but she doesn't try to dress and undress them yet.She just talks to/with them,and shows them her other babies.Make sure to make her some dollie blankets as well. I have doll patterns going back to when my DD was little 44 years ago,and for all sorts of dolls. Check your thrift stores also for old doll patterns,ours has lots of them from time to time. 2 years ago i made a wardrobe for my niece for her American Girl doll,she was 11 at the time.She was thrilled!!
