I have pulled together a few ideas which you may just be able to get in time...
Love Hearts/Dress Pattern Oyster Cardholders £6ea
or Custom Designs for £12
Why not book a class for your lovely lady. You can choose from a Vintage Hair/Make Up super class to a more specialised Finger Waving one on one class. Prices start from £95-£370. Or a simple voucher would definitely tick the right box!
