I really dont get the whole "pokemon dont wear clothes" GF schtick. They even break this rule in a quite a few of ashnime episodes. What the issues? They are afraid it would humanize them more?

I think it is a missed opportunity, poke-speicific clothes look really cute/good on many of them. Hell, Greedytendo could sell 1 toy and 34564358 dress-sets for girls, literally pints money
