Holly, thanks, that really is great advice. Ill probably use that line "wve got the accomodation sorted, but regarding the suit money is a little tight". Good stuff.
Unfortunaltey the wedding is about 2-3 hours away, and i dont have a licence (i just got my l's a few weeks ago) so going down seperately isnt an option.
The most annoying thing is knowing how well off they are, and not offering to pay for the essentials for their bridal party who arent very well off has really made me think so much less of them, its made me sad!
