I've heard that it is possible to get a wedding garter custom made in the colour of your H2B's football team. Where could I get a garter in the Chelsea FC royal blue colours?
What a great idea! There's a company in Scotland called Wedding Garter http://www.wedding-garter.com. They have garters in various colours but will also personalise with different coloured ribbons - so I'm sure they could do a design with royal blue ribbons.
I would also recommend trying the Chelsea shop as they tend to sell all kinds of things in Chelsea colours.
I've just found a Chelsea garter which looks like it could be perfect at http://www.jacquisbridal.co.uk/garters.htm
