My dolls all have their own names and it depends on the doll and character that come to mind when naming them. Sometimes it's almost instant other times it's after the character and faceup. I already have a few storylines going so any new dolls (other than tinies, they're my happy dolls, so they don't usually get a story behind them) are fleshing out those stories. For instance, my fairies all have flower/plant names. When I got Hemlock, I went through a bunch of "poisonous " plant and flower names. But when I got Tea Rose, I knew her name instantly before I even bought her. Sometimes just going through baby names and/or a thesaurus helps to inspire names. Other times it's just what comes to me. I've searched for a specific theme for my dolls before and then came up with names based on what popped up. It really depends on the person and doll. As far as just using the sculpt name, I feel like it's a bit impersonal? Like, here's something that's just going to sit on a shelf and I'll look at it maybe twice a year type of impersonal. Now, this is just my opinion for how it feels to me personally. If someone else likes just using the sculpt name, all the power to them and what they're happy with.
