Aggh I have until Thursday to find a dress

[IAmOptimusPrime]

So I posted earlier about a 20s wedding I'm going to and have just been told that my dress isn't very 20s (I admit it isn't) so now have doubts about wearing it as it is long and backless, much more 30s.

Wedding is in Spain and I leave on Thursday. Please help as the couple are quite serious about the theme and I want to look nice.

I am tall size 10 and have max £100 and really don't want to look like I'm going to a fancy dress party!
What does anyone think of these?

yellow

white

white

All gorgeous but I think the yellow one is more suitable for a wedding, isn't it a bit of an etiquette faux pas to wear white for a wedding unless you're the bride?

Or you already know that the bride is wearing another colour? I wore red and wouldn't have bothered what colour anyone wore.

Ok will steer clear of white. I do love the yellow but may be too short.

Am now loving this as well. Oh the decision!

green

The colour's lovely but it looks like an octopus on your fanjo area, sorry!
