I ordered two suits from them this summer.
The measurement process is inaccurate and the suit was un-wearable. Granted I made the measurements, but honestly, there should have been more guidance and examples in the instructions. I strongly suggest you use an existing suit for making these measurements, and perhaps add some space.
The company remade the suit at no cost to me, which I thought was terrific customer service. I could easily take the ill-fitting suit and add inches here and there to my profile, so the remade suit ended up pretty close. Close enough for me.
The second suit was delayed and that was a good thing until the measurements were finalized on the remake and delivery of the first suit. They forgot to include a vest, but made one up. Again, good customer service.
Decent Fabric Selection--probably 100 different fabrics, which is smaller that Tom James Clothing Company, but remember TJ charges you $2,000 for a suit and its made in America.
Good Customer Service--granted the two suits were screwed up, but Harry's remade on and shipped the vest as ordered, albeit a bit late.
Great Cost Savings--A custom made suit for $250? Sounds too good to be true, but its not. There are some hurdles to go through like time and screw ups, but you really can't beat the price. An off the rack suit runs me about $400, which also needs tailoring, so I'm willing to put up with some BS to save some money.
Custom Tailored Suit--Once you have the measurements dialed in, the suit will fit like a glove. See below for how to accomplish that.
Delay--The suit takes about 6 weeks to make.
Delay in Customer Service--The folks at customer service will get back to you, but it might take a few days, and often involves an email exchange, so your problem won't be resolved for a week or two.
Suit Not Fully Customizable--I like cuffs on my pants, and this is not an option, nor is the placement of pockets on the vests, color of lining or button construction. Perhaps if one made a point of this in the comments section, it would work, but the customization options are limited. For $250, I'm OK with that.
IF YOU DECIDE TO ORDER A SUIT DO THIS:
First, order one single really inexpensive suit first. Don't order multiple suits. Wait until you've got the measurements dialed in.
Second, when filling in the measurements, pay close attention to that detail, and use an existing suit for the measurements.
Third, when filling in the measurements, I might add a couple inches to the pants (to make it easier to tailor the hems) perhaps an inch in the waist and jacket length (again, to make it easier to tailor) and pay close attention to the rise measurement. Too long makes it hard to walk and too short is really uncomfortable.
Fourth, expect the suit to be screwed up when you get it. Hopefully, you were reasonably generous in your measurements, and it can be tailored. Harry's will pick up the tab for tailoring, up to about $100 I think. If its more than that, they will remake the suit.
Fifth, once tailored, make a note of what your tailor has adjusted and modify your measurements in your on line profile on the Harry's Web Site.
Sixth, if you order a second suit, it ought to be dialed in pretty close, but again, your measurements might need some slight tweeking for the for the second suit--take it to a tailor, make the adjustments, and modify your profile again.
Seventh, after ordering two suits and adjusting your profile, you ought to be really dialed in.
THE BOTTOM LINE
The bottom line is that Harry's Suits isn't for everybody--if you expect a suit tailored to fit like Tom James for $200, then you'll be really disappointed.
On the other hand, if you want 3-4 suits which are super cheap and fit well and have features like vests which you cannot find in the store, then Harry's is for you. I don't buy all my suits there, but there is a place in my closet for their suits, and if one gets ripped or stained, its super easy to get a replacement on the cheap.
