Is this dress ok for a (mini) festival?

[Itsreallyallovernow]

I'm going to a (very small scale, no Glastonbury!) music thing in my home town next weekend. I've recently lost a lot of weight (now a size 12) and even more recently (yesterday to be precise!) split up frpm my long term partner...so this will be my first time out post split and seeing my friends, so I want to look and feel good, so that I don't end up a tear stained mess by mid afternoon...

So I've recently bought this dress...assuming the weather is reasonably warm would this be ok? And what would you wear with it? Flat sandals or something more like white laceup pumps?

Also of the weather is cold/ rainy (a distinct possibility!) what would you wear instead?

I'd wear white pumps/trainers but I guess it depends on what the weather is like and how muddy it will be. Also would work well with a denim jacket.

You'll look beautiful! It's a lovely dress. I think it'd be good to have closed toe shoes if there might be dancing/spills. White embroidered trainers will give it a bit more edge, and if it's cold I'd wear it but also stick on an unzipped barbour, invisible tights and some biker boots.

Have a fantastic time!
