WWE Stars Lana and Rusev -- Perfect Wedding No. 2 in Bulgaria ... Except for that Black Eye (PHOTO GALLERY)

WWE superstar Rusev wasn't picture perfect with a black eye ... but that didn't stop him and Lana from saying "I do" again -- this time in Rusev's home country of Bulgaria.

You'll recall Lana and Rusev planned 2 weddings -- a romantic ceremony in Malibu back in July and now over the weekend. They went all out ... Lana's dress was a whopping $75k. We're told the lace alone was a cool $15k.

Check out the pics .... it was a traditional Bulgarian wedding that started at a Greek Orthodox Church followed by a reception with all the fun traditions -- including the groom showing up to the bride's house and paying her sister, mom and bridesmaids for his bride.

It's unclear how much Rusev paid ... but we're betting Lana's worth it.

Next stop ... east Africa and Dubai for their honeymoon.
