This is a question that I get asked every day. My answer is; go ahead and lose the weight! We can always take a plus size dress in, but cannot let it out. Manufacturer’s do not give us much inseam allowance to let gowns out. It is always better to order the size by your measurements at the time of order placement and take the item in if you should lose the weight. Keep in mind the timeline for ordering. Most manufacturer’s on a special order require 6-8 weeks, so even if it’s only 5 pounds, it is going to make the gown look better when it comes in.
