I agree with Animaldoc...a month is plenty of time to make alterations and these places are really quite used to having to do so. You'd be surprised how many brides gain or lose weight due to pre-wedding jitters and need to have that dress altered at the last minute. I'd say keep with it until your dress is ready...you should have at least one fitting before they completely finish it..and then go on maintainance until the wedding. You can always finish taking off those last few pounds after the happy event. Congrats!
