not huge, not flat

[frindle]

Hello.
Is the bolded part talking about breast or something?
Or not ourstanding, not dull?
I'm not sure. Please help. Thank you.

Throughout middle school, Miranda, Ella, and I were pretty much our own little group.
Somewhere between super-popular and well-liked: not brainy, not jocks, not rich, not druggies, not mean, not goody-goody, not huge, not flat.

I think it is referring to their breasts.
