Hybrids Fanff and Tianba Iris

A huge bit of if they'll both work is personal preference. Example: I really don't like the look of a smaller neck than the doll was made for, to the point that if I can't find anything perfect I'd much rather buy a body with a larger neck and sand it down to fit. On the other hand, a smaller head just won't sit properly on a larger neck. So if one of the necks is going to fit with Iris it'll be the 9.7cm (and it'll depend on how accurate the measurements are; she might sit awkwardly if the neck is actually a bit bigger and she's a bit smaller), but Sel will only work if you are okay with the smaller neck look - and might require some sueding to sit properly.

 

I also wanted the same thing, but Tianba Iris neck is 9.5cms and fanff is 9.7cm

It will not fit

I would choose a different body or get both with Sel.

 

I have my Iris on my fanff body. I have to check which body it is, but mine personally fits well (other that I ordered the wrong skintone )
