WOW!! Your cosplay of Rosalina is definitely the best I've seen by far...I have a few questions, if you don't mind...? I am also trying to make a rosalina costume for my upcoming 20th birthday party. I really like the way that your accessories turned out! My questions are: what did you use, where can I find it? Also...if you have any suggestions about how to do the makeup, that would be awesome!!
for a lot of the accessories and gems I made my own shape out of sculpey, molded it and then cast it out of clear resin. I used a wooden star from joanns and foamie as well as polystyrene for the chest and crown
