Kata,
Also...here's another alternative, this is along the lines on what i did for my jumpsuit...I went local. 8)
At the time when i was looking for a jumpsuit, both SGB and BM were bogged down with orders and since I already had the jumpsuit info [material type, pics of the various jumpsuits both fanmade and movie versions, double zipper, my perfect fit cwu-27p military flightsuit and the material], I went to my tailor and gave her everything i had and asked if she could do it. She could and did.
Got me a simple generic neckseal and boot spats as well [until i get the proper ones with the correct material], on top of the jumpsuit and she even threw in the velcro stitching for both my Batninja vest and jumpsuit knees and it's a perfect fit to boot, all for a very affordable price.
Again, like I said, its just an alternative but you could try your local seamstress...who knows, might be even convenient for you as well, should you have or need alterations done, for whatever reason. :cheers
Again, good luck!
Stay safe,
Tim.
