Okay ladies! I need some advice! My dress budget is $1500 max including alterations and accessories. But I'm always looking for a bargain! I've visited $500 sample sales with no luck, but found the ONE at a local bridal salon and totally fell in love. I didn't want to take it off and haven't been able to stop thinking about it! Unfortunately, it was full price and over budget

This Martina Liana gown retails at this store for $2485, which is doable but considering I'm only wearing it once...it just doesn't feel right to spend that much money on a dress. I've called other salons asking if they can order the dress so I can compare prices and try to get a better deal, but have had no success.
I saw this gown on Oncewed.com, Preloved.com for closer to $1100 and there's Tradesy.com as well. The gowns all say that they are in good condition with no rips or stains, only slight alterations made...but my concern is that like buying anything on the internet, I'll be disappointed when the dress arrives. Has anyone used these sites before or have any advice for buying a used gown?
