Please help with this order?

I ordered a Roxas cosplay outfit fom ebay on June 5TH and it is suppose to be coming from Hong Kong Standerd Shipping by airmail. I wanted to know how long it takes for it to come from Hong Kong all the way to the us. I live in a small town called ambler pa on fracis ave. I also wanted to know if they will deliver it by UPS or USPS
