Here you go Mel, the boots you want are in both shiny black and flat black (pu), you can choose in the drop down.
And for leggings I am currently out of the 18038 and it would take at least 2 weeks for me to get more. I have included what I do have right now here. The chain back and the other mesh back are very sexy!
This is what I have right now that can ship with your boots, the tighter the better with these:
Some of these can also be worn backwards so the detail is in the front.
xs in the 18035 (fits more the size of a small then xs)
small in 11860
small in 18159
xs in 18121
Email me with any questions.
