I got my belt/harness set from Wayne Factory on etsy and then darkened them to my liking. PropsNStudio was the gold standard among a few Cap groups I'm in for a while but their store has been on hiatus for a while. 3GeekDesigns (via Facebook or IG) also do runs every so often and are probably more screen accurate than Wayne Factory but less readily available.
Here's my Endgame suit
Base suit from WSL, ab tabs and urethane star burst from 3GeekDesigns, gloves from LFV, weathering and scale accents done by me. I can go into more detail on how I did that if anyone's interested.
