First try at custom mandalorian

Hey guys i am a noob to this scale of costume making so i have a few questions on items.

1.what is a good suggestion for the vest as in leather where to buy etc. anything

2.for the jumpsuit i have found 2 items that look great on amazon.com and yes i am using a 2 pieace flightsuit but i can hide that fact.
here are the two items.

Does the shirt have sweat wicking material over the chest? The image is small and I can't be certain if it's a crye combat shirt or something similar.

i beleive the center is crye combat or a mixed blend

If it doesn't pan out it can be used for other costumes very easily. I kinda wanted to go lightweight on cloth type material because i can do metal fabrication the shoulder armor will be metal and i like a heavy armor look so lightweight cloth would be great.

The center of the shirt is 50/50 blend of cotton and nylon

I've always considered using one of my combat shirts for a custom mando design I had awhile back as well. The shirt will definitely help with keeping you cool while your trooping.

any tips on gauntlet making?

Also any tips on the vest for the armor to attach. Would it be better to make from scratch or if you know a good place to buy i kinda want a leather look
