I'll let you in on a little secret on my naming strategies for dance troupes/children/etc.
~Don't go too "cutesy".
Here is something you could do, I did a similar thing when I came up with the name for a dance troupe:
~Think of all of the names that describe plus size, and list them all: Queen, Plus, Full Figure(d), and so on and so forth.
~Think of things that RHYME with all of the full figured names.
~Think of phrases that normally go with the rhyming names, instead of the actual plus sized name.
~Find a combination that is good together.
If you didn't understand that at all (laughing) here is what I did with the dance troupe that I am currently involved with:
Cairo Technics (instead of Pyrotechnics)
