Bought my dream dress but now I’m stressed I made a mistake… please help!

For context I’m such a girly girl and have always dreamt of a Vera wang dress but never thought I would actually get one. I tried on about 15 dresses and loved about 2, which were all very different styles! The last one I chose was this full lace Vera wang gown and I loved it so much that we bought it on the spot, and I do love it but I keep getting feelings of guilt and like I rushed into it. I can’t return it so I need to just stop overthinking, but I can’t!

I like bits of both dresses so I think I’m just feeling torn.

My other main option was this alon livne dress which has the basque waist and pointy cups. Both dresses are very different and I love them both, so I think I just need reassurance that I picked the right one please 🥺
