NO!!! Keep it! It's gorgeous!!!!! It truly is beautiful. You're having dress regret, I had that too! My dress is the San Patrick Rivoli which is somewhat similar. Mermaid lace, not beachy at all. Once I tried it on again I fell in love just like the first time! I think when family isn't 100% on board, it makes us rethink our choices. My family was the same but in the end, it's your wedding and you need to love your dress, not your family. You don't want to regret not picking the dress you loved in 20 years! Be confident in your pick! Hope everything works out well!
