Rehearsal Dinner Dress!

If you have any concerns that your first look will be less that spectacular, you might consider having the bottom hemmed up just to tea length, which may give the dress new life after the festivities are over. You could potentially wear it for Easter or as a summer dress. I think he be in awe on your wedding day no matter what you wear before

Both dresses are good, but I have to agree with the majority here.

I feel this! Can be hard swimming upstream on these forums.

For someone who clearly knows what looks good on her cause both dresses look great, don't worry about similarities. A similar silhouette is bound to happen if you know your body type. The rehearsal dinner dress is clearly more casual in style and fabrics, so it's a win in my book.

The decision on wearing that reception dress favors you just doing what works for you. Your sister's concern sort of prompts people to follow what she says. But in reality, your fiancé will appreciate your look on both days and probably wouldn't notice any similarity either.
