However it did put me in mind of this dress from Toast which I think would add an easy glamour to Sally.
This Anastasia dress has a soft cotton velvet bodice and a fluid, weighty, glossy silk satin skirt. Now that I've blown the budget on the dress (£132.13 - the odd cost is due to the VAT reduction) I popped to New Look to accessorise.
Multi Jewel Bracelet £10 New Look
These satin flats £15 (available in black, midnight blue or fuchsia)
And in case it's a bit chilly there is a lace bolero £25 from Topshop
