No problem - I used to do that, too
I would invent mannikins that actually looked like real people (stomachs! thighs, butts, you get the picture

and then I'd have stylists dress them in the clothes that look good on them ... that would save shoppers a lot of time and trouble, trying on stuff that doesn't fit.
After you've studied a bit, we can try to converse

Spanish is the easiest, by far, of those three... German is the nastiest... in grammar, anyway.
What would you invent?
