Me and My friend bought the same 2 dresses for an event?

We have this school event tonight!!! We were talking in homeroom about the dresses we bought, and she was describing this one that I bought. I was like OMG we have the same dress! It was cool and stuff i was like haha and she was just like i will just wear my other one and she described it to me, and it was the exact same second dress i bought. its crazy!!! we decided to make our decisions independently about what dress we will wear and then whatever happens, happens and we will look back on it and say haha yeah we wore the same dress. do think thats an okay decision? we aren't going to be mad at eachother or anything if we do end up wearing the same one...so yeah. do you think it will be okay? i told her im wearing the second one and she said ill make my decision independently but i dont want it to be unfair because i made my decision first. i really like the one im gonna wear so i dont really want to compromise and wear the other one, but im being pleasant about it.
