Going to a mamma mia tribute type thing in a couple of weeks and we're dressing up In desperation I have bought a black top with lots of silver sequin type things on it from the charity shop for £2.50 but if something better comes along ... I don't want to fork out a fortune (had a look at some of the outfits on the dressing up website but they are quite expensive!) but want to look as if I've at least tried to make an effort!!
