Like a previous reviewer, I found this on the slightly smaller side, but unlike the previous reviewer, I was OK with it. I have a Big head and I just push the hat down a bit. I think the hat will eventually stretch out. I haven't worn it out yet, so I can't say if wearing it tight gives me a headache or if the hat slides up after wearing it a while. It is really cute though. Just like the picture and the color matches the outfit for which I bought it.
