wear a simple dress of one of the colors of the season
Many brides feel a need for a "party dress" that is shorter and easier to dance in for the reception.
Changing out of your dress before your reception is really a personal opinion. Alot of women will wear their dress for at least the first part of their reception so they can get the pictures of the cutting of the cake and do other traditions, then change out of it for dancing, eating, etc for more comfort.
At a traditional bar mitzvah reception, party dress are usually worn for the girls, and a nice shirt for the boys.
its up to the bride!
If you are having a somewhat formal reception in a tent, restaurant, hotel or somewhere that guests are expected to dress up; you can wear your wedding dress (people will want to see you in it) but if you are having a laid back event then don't wear your dress unless it is a casual dress without a train. You can just wear a pretty dress in ivory, blue, pink or pale yellow that isn't a wedding dress.
The color of dress that is acceptable for a wedding reception would all depend on the colors of the wedding. If the person is a member of the wedding party the bride may have choses a set color or dress. If the person is a guest they would not want to clash with the wedding party.
It depends on what she wants. You should ask her, not strangers.
What is considered a "good" wedding dress to wear during the reception depends on the bride. Some brides prefer to wear the same wedding dress during the wedding ceremony and the reception. Other brides prefer to change into something different, often something that's easier to move around in as they may be going from table to table greeting guests and/or dancing a lot. A "good" wedding dress to wear during the reception is whatever suits the bride as far as style, comfort, and cost.
Yes, you can certainly wear the same dress for an an afternoon wedding and an evening reception. It may be more suitable to wear something a little more evening-appropriate, even if you're slightly overdressed for the wedding (rather than vice-versa).
Women can wear either a simple dress or a skirt with a nice blouse. Men will be fine in dress pants or khakis with a button down shirt.
Only if she is part of the wedding party.
First of all, congrgulations! And second of all, no. The thing is most guests at the wedding pay attention to not only the bride, but the intermidiate family of the bride as well. If it's a money issue then I suggest wearing an older dress to the reception. maybe a more comforatable one if there is going to be dancing. But at the same time it is the reception of the wedding and i suppose you could wear a different colored one. I sure no one will really pay huge attention. As long as you look nice. You should do different things with your hair at the reception tho b/c you don't want to recreate your look at the reception from the wedding. you can wear the same dress in a different color as long as you wear different accesories, hair, makeup and nails. I hope this helps
