I've been offered a new job (yay!) and the dress code states a white blouse. To me 'blouse' means something with buttons but my mum says anything that's not a t shirt is a blouse. Who is right? I've bought [[http://www.matalan.co.uk/product/detail/s2601728?id=S2601728&color=C359 this]] but don't know if it's too casual.
