Dont worry about what it says. Most suites have those 'dry clean only' labels on just to prevent custys trying to clean themselves, then causing problems and complaining to the manufacturer when it goes pear shape. Its a get out clause, and I suppose from their point of view quite sensible.
Yes there are some suites than can only be dry cleaned but a professional cleaner can tell which ones! Although in saying that I have done quotes before now where other so called professional companies have refused to clean a suite (because they couldnt identify them corectly), and we have cleaned them with absolutely no problems, its bizar. No training ever, me thinks
Judging by the pics, wet clean should be fine.
