Hey, has anyone bought their dress then decided they get it or just me? I loved the dress for so long and put my deposit down (half the cost ????) in January, it will take 6-8 months to come in and I'm not getting married until August 18! I've now decided I don't like it and I'm getting really anxious! Any suggestions xx
