AIBU to alter the dress without telling the bride?

[WeAreEternal]

A friend has asked me to be a witness at her low key wedding marriage ceremony.

They decided to get married but don't want a big do so are organising the whole thing in a month, basically it is just a registry office ceremony with a couple of witnesses and immediate family and close friends, (I think she said there will be 11 people there.) then a meal at a nice local restaurant after.

How did the wedding go?

Sorry for the late update, it's been a busy week.

I had the dress altered, it looked great from the front but I didn't like the back. But I bought a lovely shawl to hide it as advised.
Seeing the other witnesses dress did make me feel quite self conscious, but in the end it was all ok.

The marriage (we weren't allowed to call it a wedding) went beautifully, it was a very short ceremony, we then went for a couple of glasses of champagne in a nearby bar and then for dinner in a lovely restaurant.
It was a really nice day, very casual and easy, it was probably the most enjoyable wedding I have been involved in as there was no stress it was just very simple and nice.

Good news Eternal :)
