What icing to use on a barbie ball dress cake

[NutterlyUts]

I'm making a cake for a friend's 4yr old that'll be like this but as sleeping beauty in this pic

I'm confident on making the cake, but I'm unsure what icing (royal/fondant etc) to make her skirt out of? I'm planning to make the cake chocolate.

Use that gooey white icing and colouring paste

buttercreme?

no, you buy it ready made in teh supermarket

hang on, I'll just look in the cupboard

it just says "Morrisons ready to roll white icing" on the packet, lol.

I always get mixed up between fondant and royal. I think its fondant you will want, the soft Christmas cake icing style IYKWIM

Ah i know what you mean. I thought that was royal?
