Hi: I worked with the Historian of the Infantry Division my Grandfather served with during the Big One. She said the best thing to do is let the dry cleaner know what you're doing and that the item is fragile. Some dry cleaners won't take it for liability reasons. Others will take it and dry clean it by hand. When you get it back, I was told to never never never store it in a plastic suit bag. She said get one of those woven fabric suit bags that are air-permeable. She also said hang it on a hanger with large diameter arms, to spread the weight of the uniform across as large an area of the shoulders as possible. That reduces the stress on the stitching. She said it is best if the suit bag doesn't touch the uniform - suspend the uniform within the suit bag if you can. Never fold anything or it will be permanently folded. Keep it cool and out of sunlight.
Hope you've found a reasonable answer since your original post. Please let us know what you learned!
