All through my childhood I found tops were too short in the body and often too long in the arms, owing to my long torso.
Now my daughter is having the same issue.
I am pretty keen on her not wearing leggings as pants, but she has quite a few pairs now and it is getting harder and harder to keep her adequately covered because she is a tall girl (taking after DH, not me) and growing fast. A tunic top I got her last year now does not completely cover her bottom. I went to (Australian) Target and Best and Less looking for some long tops - just something like a long sleeved Tee - and found nothing. We did get her a banded cap sleeve Tee shirt but even that is not going to be adequate for very long.
She does have a couple of sweaterdress which she wears with leggings and over a tee but sometimes she just wants one layer on top.
How strict are you with kids and leggings coverage? And is anyone else facing this problem?
