Nature's Own Bridal Bouquet

I discovered this flower right at the bottom of the garden hidden away behind one of the small trees. I think it is one of the prettiest flower I have ever seen! Does anyone know what it is? I've never seen anything like it before. It looked so delicate it reminded me of a bridal bouquet!

Colour and contrast tweaked a teeny bit.

Full view recommended, thanks!

EDIT - Thanks to who identified it as Thalictrum aquilegiifolium, or commonly known as Meadow Rue.
