My 5yo son wants to wear skirts - I don't mind but I had a few questions

My son turned 5 a few months ago. Since then we've been letting him pick his own clothes once a week. At first he would put together his existing clothes (he once picked his turtles onesie and rocked it) then asked for new clothes he saw on TV or his friends wear. Of late he's been asking for female clothes, skirts especially. It's mostly stuff like "I want that skirt Emily wore on Tuesday" which is super specific and helpful.I don't care what he wears as long as it covers him and makes him comfy. But it's there something in terms of gender identity or am I overthinking it? He hasn't mentioned anything about it and I haven't brought it up with him because he's only a child. I think his skirts obsession is a fad and it's more driven by his friends than anything else. I've not bought him any girls clothing yet and put it off by saying things like "it's cold today" or "you look so handsome in that shirt".To be clear, I don't care how he dresses, and how he feels about his gender. I mean I obviously care about he feels about gender and will support him regardless - but is he old enough to feel things about his gender? Will his peers mock him if he wears skirts? Will inaction on my behalf affect him negatively later? Will me complying have any effects later?I haven't asked his pediatrician yet because I think it's still early days to panic but as I'm writing this I feel flustered haha. Any opinions?Edit: these are some good answers, please don't down vote them if you disagree? via /r/Parenting https://ift.tt/2BJp1Zq
