What colour goes with RAF blue number ones?

[sonotmumsie]

for a wedding dress - white/ivory/champagne? For a bridesmaid dress/ushers and colour theme?

Well there we go I had no idea! Yes I bet it looked very smart with white gloves and belt

oh no, the dress has £100 off - I should get it (and shoes!) shouldn't I?! I can return for a full refund

I'd get it if I were you, sonotmumsie. Like you say, you can return it if necessary.
