'Gala' or 'Grosvenor'?

Which is it?  Opinion was divided today when we had this with our salad for lunch  Maybe it can be either.

Bride to be collected the shortened dresses for the bridesmaids today and brought her dress along to be made bigger!  She has put on weight since buying it - usually the other way round.  Will have to replace zip with loops and ribbons so she can be laced into it.  At least that is the theory.  Needs a bit of thinking about!
