Firstly avoid sending stuff to the cleaners as much as you can. Spot wash any stains with water. Invest in a clothes steamer. Switch suits and pants often. The next thing is it doesn't matter if it's a 300 or 800 suit. It depends on the material. Never go above 120 or below 100. The super 140 and 150 get shiny and wrinkled quickly.
Lastly I will send my stuff sometimes to deluxe cleaners in Clifton nj they are excellent or for very expensive suits 1500 and up to either madame Paulette in new York City or for a wedding gown and something exquisite to rave in Scottsdale Arizona they are world famous. I live I lakewood and have tried everyone it's all the same garbage.
