I had a miserable experience trying to return a dress for my graduation in May. I purchased a dress (not knowing it was coming from China) and it took upwards of two weeks to get to me. I received it a few days before graduation. I'm glad I got a back-up dress because the AliExpress dress fit terribly and was a bad quality--and definitely not worth $90.00. There were no tags on the dress, but it didn't look previously worn. I shipped it back to China that same day.
I contacted the seller of SPOUSA dresses because the "dispute" instructions suggested doing this first. They had given me the return address but when I went to confirm my return of the dress, the seller dragged her feet with retuning messages. She got back to me three weeks later saying she'd only give me $60USD for the dress, but fought me on the fact that the dress looked "worn" and was retuned without tags. I then had to speak to three automated customer service robots online, with no phone number available. They said they opened a dispute for me but after following up a month later, they said it was well over the 15-day period of returns.
After a month from purchasing and three months of back and forth with customer service and the seller, I was left empty-handed, have yet to be compensated for anything or given any sort of discount. I will not purchase anything from AliExpress again, and if you choose to, please do not purchase anything from the SPOUSA seller.
