Sequin cardigans, are from many years in fashion, I have seen so many of them that they became to cliché. Sequins always are appearing in different combinations in evening outfit, not too often people wear them with casual clothing.
Few months ago, "The Gossip Girl" character Serena appears wearing lovely dress which used to have sequin sleeves. I though this is exactly the dress that I could also wear, simple but with "twist". I thought that I really want to have something like this.
