This is the closest I could find… maybe see on some buttons to make it look more like the original?

So you may have to DIY it. Get a light blue tracksuit, then get some navy blue iron on vinyl. You can get the vinyl on Amazon or a craft store like Michaels. The design looks pretty simple, just elongated triangles… cut them out, lay them on, then follow the instructions to iron. A lot of them say you need a cricut machine, you can just cut them with scissors. I’ve used it for a different costume on track pants before… it’s not gonna last forever through multiple washes, but you can get a few wears out of it… see below for example of what vinyl you want:

If you cut this one down the front I think it would look fine.
If you want to use an Android phone as a voice changer mic (connecting aux cable from it to your other equipment or external speaker), you can use our apps.
Plug in the aux cable, and then press the Record button - you will get real-time output (the 12-voices usable for Darth/Kylo/Bane/Stormtrooper/C3PO etc.) - each of the voices are individually customizable in real-time.
There is a small latency on android - and that can trip up some cosplay - so maybe keep the phrases short (so your own voice on external speaker doesn't trip you up).
