So, not sure how to explain this thoroughly. I remember a story a read a while back, it was a one-shot about Dash wanting to be taken seriously by stallions because everypony just assumes she likes mares because of her mane, so she dyes it a different color, which doesn't change anything. I've tried searching for it but I can't seem to get anywhere with my search. Anyone know what story I'm talking about?

Is this it?
