Having a son growing up in a purse shop

So...my 19 month old son was in the store today and within 5 minutes, he was wearing a kid's monkey watch, put a breast cancer awareness hat on his head, and got his fingers into some lip gloss that proceeded to end up all over his face. I wonder at what point will it no longer be cool for him to do those things or at what point I will no longer want my son to wear a woman's hat and lip gloss all over his face? It will be safe to say the former will probably happen first as I'm comfortable with whatever route he goes in life. But for today, I found it a great joy to see him dancing in the middle of the store (Sting was playing on the radio), the breast cancer hat on sideways like a little rapper, and he couldn't have cared less who was watching. Wouldn't it be nice if we could all do that a little more?
