fur is an instant-no.
I agree with this. My wife comments on how it's ok for boys to like red - I'm fine with that since my other 3.5yo son loves red everything (his twin loves blue so the contrast is good for them). CARS backpack - red. Jacket - red. Toy cars - red. Bike helmet - red. He says he's going to drive a red Mustang someday. All good. I draw the line at red pants and red crocs. She thinks it's ok. He's only 3.5 but still - over my dead body.
Verbally disagreeing with my wife enough times has led her to give in for many situations.
I could feasibly see the red pants...but are we talking about any type of pants that are red or something like red jeans?
I would agree on a formal pair of dress up pants being red or a pair of jeans...
wind pants, sweats, shorts...not so much...
My kids have red / blue / black crocs...and I personally don't see any issue with that...and they have never been mocked or picked on for such a thing...
I would still say no to anything with fur unless you're a pimp or live in Russia or both.
Ok what if you were FROM Russia and lived in south Florida...and your name was Vladimir?
