Impulse buy!

I walked up to the library this morning to take my U3A Genealogy Group.
I was a little early and had a little wander round the shops and fell in love with this top which is very floaty.
I was not sure when I tried it on until it was pointed out that I had put it on back to front! (my excuse was that the security tag was covering the label!)
I am going to the theatre tonight to see "The Mousetrap" and of course I hadn't got a thing to wear with my black trousers!!
It will also be useful for my holiday as it is light and easy to pack.
I think I have talked myself into it and I don't feel too guilty.
