I had my surgery on February 21st and I am standing up in a wedding on August 10th. I was 215 lbs. to begin with and today I am 196. I don't know what to do about ordering a dress? I was wondering what a 6 month weight average is for people with a similar size?

I would suggest you wait and order your dress closer to the event. You can then order it at/just below what size you are, and order that size, after confirming with at great seamstress that she can size it down ahead of the event.

PS - for you, it may be a good idea to take lots of pics at different angles and measurements, that way as the time to get the dress you can also get an idea of not just how may pounds you are dropping, but where it is dropping from. It could be important for the dress (and I assume you thoroughly plan to rock this dress!).

I am in the same boat, but I am the bride:(

I was sleeved 2/18 at 217 and I am curious about this too. I'm going to a friends wedding in August and all of my college friends will be there.
