Traditional Dresses.

I’m the newest employee at my company and two days ago I read an email that was forwarded to me from my boss about the annual Christmas party! Hmm. I was surprised because I’m not into parties. I asked about it and it looks like I'm required to go. I was told it’s usually fun. The theme or the idea of this year’s party is wearing traditional costumes. Seeing the looks on the faces of my female colleagues made me feel like this party must be something different because they were so happy just talking about it and preparing for it. They even took the last hour of work on Friday just to look for traditional dresses online ;)
I was not going to do the same until I heard them laughing together, so I took a look and to my surprise I found that I liked those dresses very much. Unfortunately I’m not sure that the traditional dress I liked will be easy to find anywhere. One of my colleagues picked a traditional dress from Africa and she said she can borrow it from her Nigerian friend. Lucky her. I wish I had a friend from Armenia, because my favorite dress is Armenian.
I hope I’ll make up my mind and pick something soon. If I don't I’ll be the only girl at the party with a non-traditional dress and I don’t wish to look odd, especially because I’m the new girl there.
