How do I even out my tan in time for wedding?

[Happypeas]

I'm due to be bridesmaid at the end of summer. I'm wearing a mid shin length dress that is sweetheart shaped front no shoulders. I've tanned most of my arms and chest but have a massive tan line! Also bright white legs and very brown feet. I've got a month to sort it. What shall I do?

I don't have time to sunbathe hours on end as have 3 children to run about after.

I'd get a recommendation for a spray tan, and go and try one before the wedding and see how it looks. I'm sure someone good can make it all look even
