Not odd at all! Go with whatever she'll actually wear.

Both my kids (boy and girl) wear a mix of "boy" and "girl" clothes. In my experience, the leggings wear would the quickest.

If she likes them I don’t think it’s weird at all. FWIW I have girls with sensitive skin and the girl leggings really aren’t that tight. But my kids wear a mix of “boy” and “girl” clothes.

4 year old girl has been wearing many of pass down boy pants from her older brother, and they got some tiny holes in the knee area due to wear & tear & she roughs play. I am going to get some new pants for her. She has sensitive skin & eczema on her legs, should I get those boy winter fleece pants for her ( more roomy and breathable)? Girl fuzzy lined leggings are cute, but I am afraid that may irritate her skin due to tightness.

Is it odd to buy boy pants for girl?
