In my case, I am not sure it would be worth it to get a refund even if I could. I bought the suit for $200 which is by far cheaper than any of the suits I have seen for sale.
That said, if the community says it is not approvable, then it's not approvable. I am not sure though that it was a waste of my money. In the future, as my finances permit I would like to purchase an armor kit that could be approved. It's a matter of what I can and can't afford at this time, and this suit was something I could afford right now.
