In my line of work I wear suits at least five days a week. I have bought suits from various vendors both brick-and-mortar and online. What I have found is that, for the price, one simply cannot beat the suits at Men's Wearhouse. Every suit I have bought there has lasted far longer than any other I have purchased and the tailoring services have been impeccable.
Although the quality of the suits has been top-notch, the element that truly makes me a loyal customer is the level of service I receive. The store keeps track of what you buy. I have sent my fiancee to buy me some shoes when I was sick and because of the tracking that they provide, she was able to find the style and the size I wear. My fiancee and I are greeted by name and are attended to without pushy sales, but pure and simple, excellent customer service.
I cannot recommend Men's Wearhouse highly enough.
