Miley still has a bit of a Southern accent, and she is speaking very quickly here, which makes some of her pronunciations difficult to understand. :-)
The designers she listed are: Jeremy Scott, The Blonds, Cavalli, and Kenzo. She also requested unique designs: "A lot of custom stuff too, things that I wanted."
"I have super A.D.D., obviously." A.D.D. is an acronym for "Attention Deficit Disorder," which is a controversial medical condition in the U.S. Not everyone agrees if it is a real medical issue, but right now in the U.S., if you get diagnosed with A.D.D. by a doctor, you can take medication to help you concentrate.
However, Miley is just using "A.D.D." as slang for her hyper personality. A lot of Americans use "A.D.D." as slang this way. :-)
I think you correctly transcribed everything else she was saying. I hope this helps!
