Clare plus One

I need someone to go to Tara's wedding with. Mina had to pull out so I have the option of going alone and only knowing the bride and groom, or I can bring someone with me. When Tara calls me to tell me I can bring someone else, I start racking alternatives through my head and eventually manage to sweet-talk Andrew into coming with me. He just so happens to be within the vicinity of London over the weekend and will attempt to make it! Now I have to decide what to wear...
