Peruse vintage patterns for a while, and you'll quickly notice an oft-used convention in the illustrations: two "normal sized" models and one "mini," squeezed in to show the back view or a third option. Usually, it works just fine and dandy, like in Simplicity 2402:
There, the poor mini doesn't even get the benefit of a full body! Here's another example -- Simplicity 8535:
Sure, Magenta looks like the kind of bad girl who would beat up someone two thirds her size, but we just accept that Black is in her own separate reality and move on.
Sometimes, however, the Two Big/One Little goes horribly, horribly wrong. Take Vogue 1059:
Yikes! I don't know whether Black is petting Little Print with her absurdly large gloved hand or if she's just conjured her out of thin air, but I guarantee you she's up to no good. I predict she has a whole host of nefarious plans that she'll be sending Little Print out to enact. Is Red in on the plot? From the look on her face, I have to assume so.
This I do know: if I wake up in the middle of the night with Little Print standing next to my bed staring at me, I'm toast.
