Dress 1
Dress 2
Dress 3
Bad idea to browse sites I can't ever afford 
Anyway, it's a city wedding, am mid-40s (cough) want something chic and unfussy (no meringues), long, not completely sleeveless but doesn't have to be long sleeved either. Am dithering about whether I really want to wear white/ivory (2nd marriage) but everything I really love seems to be in those colours anyway...
And of course want to look age-appropriate but not frumpy.
I could probably justify up to £500 but not much more.
I'm getting dress blindness now - help would be MUCH appreciated!
