SOOM Dia wig size and "Crobidoll".

Hey there!
Sounds like 9-10 might be too large without alterations.

To find out what size wig will fit your doll it's helpful to have a measurement of the circumference of the head. If you don't have a tape measure but do have a ruler you can still find that number. Wrap a piece of string/yarn/ribbon around the widest part of the dolls head, usually right above the base of the ears and mark the string/yarn/ribbon where it overlaps and then lay it out on the ruler.

If the measurement is very close to or a bit smaller than 8 inches an 8" wig should fit. If it's very close to 9 inches the 9-10 wig might work with a cap underneath. This advice is for new wigs, the elastic tends to stretch out on old wigs so too big will be even bigger. Good luck and hope this helps!

 

8-9 is preferrable for most Soom Super Gems but 9-10 can work if you have something underneath to help hold it in place. Silicon wig caps can work well, I personally like Volks Pitatto rings. Volks also sells pitatto velcro so you can cut your own sizes. You could also see if Crobidoll sells any velcro for wigs too!
