for all those tall girlies

why not both?

One of my wife's friends is tall, like 6'3", and wears huge boots.

Everyone just wants to climb her like a tree

depending on the outfit, i dont think people would notice, but your right tall girls are great (source: trust me)

Or just get proportionallly sized clothes that fit and dress like a normal girl (not mommy)

If smol correlates with cute, you could at the same time become even cuter :3

It's not exactly this but have you considered barefoot shoes? They have a super-thin sole so they naturally take some height off you, compared to "normal" shoes. I wear them for completely different reasons (as a cis man who has found these to help with feet pain and posture after being a kid with flat feet), but I thought you'd appreciate the tip.

Groundies make them with "normal" looking soles, but it's all an optical illusion - they have a strip around them so the sole looks "thick", "normal" and "fashionable". Essentially a less exaggerated version of that drawing:

Caveat: they're more niche and therefore expensive. Also not everyone enjoys the idea of walking without cushioning and feeling the texture of the ground.
