To re-wear my wedding dress?

[Traceability]

I need to know the general consensus and popular opinion. After a destination wedding with just family I am having a wedding reception at home. They know we have already had our wedding - this is just a party and won't include cake cutting/first dance etc. There will be photo booth, buffet and DJ etc.

Am I being unreasonable to think I don't need to wear my wedding dress? It is lovely - but I feel too formal in it (and that's the reason I didn't want a big wedding!).

You are being unreasonable: People expect to see you in the dress, you don't need to feel self-conscious or too formal.

You are not being unreasonable: People won't expect to see the dress/won't care.

That sounds like the perfect soloution.

Wear it! You won’t get another chance to and people will want to see it!

Could you alter it in any way, or redye it?

For me it would a no-brainer - of course you should wear it! You'll never get another chance and if you love it why wouldn't you? The party sounds like another wedding reception to all intents and purposes and it's usual for the bride to stand out (even if you're someone who usually prefers to fade into the background). Go and change half-way through by all means if that makes you feel more comfortable (lots of brides do that before going away anyway), but wear your dress (minus train if that's an option). I think it's rather sad that a carefully chosen, beautiful dress is destined to spend the rest of it's time wrapped in tissue in a box on top if the wardrobe - you have another opportunity to wear it so go for it!

If you don’t want to wear the dress, don’t. The only time I’ve been to a party/reception after a wedding which had been abroad the bride just wore another pretty dress.
Another idea would be to have the dress on display e.g. on a mannequin, if space at the venue allows.
