I've ordered from Indochino as well as Tailored Man (
http://tailoredman.com/).
The quality between the two does not compare. Tailored Man is MUCH better. Given the the pricing is similar for shirts and a little bit more for suits, I wouldn't bother with Indochino. I am tempted to just throw away the Indochino clothes, but I will keep them as a backup if necessary. The fit was really bad, but to be fair the customer service is pretty good and they did redo the pants for me.
The material quality of the shirt is very poor. They are about the same price as the ones from Tailored Man, but substantially inferior. I found the material quality similar to a shirt that I would buy at the Gap, but for a much higher price.
The pants I got from Indochino were cotton. The material is okay, but not fantastic. The wool might be better, but I am not going to give it a try. The fit was really odd on the pants. I did measure carefully, but ended up with a very strange cut. For some reason, they made them skin tight on the knees.
The plus side of Tailored Man is that you get to see the material in person. They come to Calgary every couple of months. Also, they measure you in person. I found that everything fit perfectly the first time. I know quite a few people that have ordered from them, but only a small few had to have the sizing changed. And their customer service is even better than Indochino.
