I hated all Men's clothing store till I shopped at Mastroianni. Most of the Men's clothing store, the salesman follow you like a well trained puppy and no matter what you select (I selected a jacket when I tried on I looked like Chalie Chaplin,) and the salesman said it fit me perfectly. Not at Mastroianni's, they don't bother you till you ask them for help. The variety is amazing and I had to pay ten times more for an Italian suit that I can buy at this place. .
They had a store on Paradise Rd. which was their flagship store that was very popular with locals and tourists alike (which they closed and I hear they are opening a brand new store on 3055 West Tompkins-just west of Dean Martin drive and North of Tropicana soon)
The store I go to is the one on Decatur and Oakey, and it is not fancy like the Stores in ritzy casinos where the same suits cost $6000, and there are no customers..none. The salesmen are swapping flies and it looks like the British Comedy Sitcom "Are You Being Served." You get arrested for trespass if you don't show two forms of ID when you walk in.
I am a Cloth addict and I know every Men's shop in Vegas and this is the ONLY place that satisfies all my needs.
