I ended up looking at this website as a reference-
Even after following the instructions on the website very carefully, I still had a few problems getting everything to work out correctly. It was way more challenging than I thought it would be!
In my opinion, if you need a replacement body for your Dal or Byul doll, buy it from the Groove store or an official one from someone who wanted to change their doll to an obitsu body. It's much easier and about the same amount of money.
Here's what I ended up with-
(Sorry for the bad pictures, I'm very limited on what I currently have for Pullip clothes so she's wearing part barbie part Pullip outfits just to cover up. I already put the clothes on or I would've taken them off so you could see her better. Soon I will!)
Anyway, I'm happy with how she turned out despite the problems I had. The only complaint I had about the Obitsu body is that it immediately had the "tummy pop" problem, as soon as I'd taken it out of the package. It hasn't been too bad, so I've let it slide for now.
I have to admit, at first I thought Dal's weren't... how do I put this nicely? Good looking? I thought they were almost ugly with the pouty or angry facial expressions. Boy was I wrong! The pictures of these dolls don't do them justice. As soon as I get a new outfit I'll take better pictures of her, hopefully I'll be able to share how adorable these dolls truly are.
I debated a lot about getting a Dal before I finally purchased one, but I am now very happy with my decision. If you're a fan of BJDs I would definitely recommend getting a Dal.
