I am not sure a rainbow dress will go with the shoes personally ... I think the shoes need to be the focal piece of the outfit that brings it all together otherwise they will get lost I think.
What about a plain dress picking out a colour from the shoes, I'd go with the turquoise from the heel but the green from the tie would be nice too.
Maybe this? Bargain!

Then add accessories to bring out the other colours from the shoes ...

Fascinator (this lady makes them so you could get one to order in 3 different colours)

Maybe then get someone to crochet/knit you a wrap/shrug/bolero in colours to match the shoes, then you could wear it & the shoes again with jeans
