One advantage of being giraffe tall is that you have the potential to carry off a midi skirt without back-breaking heels. Asos has such a good selection of midis if you like the look.
Or alternatively, you could try your luck hitting up some op shops.
My success so far:
Country Road wool midi skirt
Sheer midi skirt
Cream wool midi skirt (kind of approaching 7/8)
I have to admit though...I'm yet to wear any of them successfully, but will be sure to show you when I do!!
