A blog post about fully bespoke suits is mildly interesting. At some point though, it gets a bit dumb... if you are willing to go through the trouble and expense of the bespoke experience, you should not be turning to blogs or bloggers for advice. You should be turning to the tailor. Imagine a blog entry providing guidance towards the purchase of a private jet or luxury yacht... obnoxious to say the least.
For buying a suit from the rack, or even just a jacket, the process is simple. As long as the neck and shoulders fit, you are in luck. Put it on, unbutton it, raise your arms all over, twist and move round. Make sure that the collar of the jacket stays wedded to your shirt collar, and that the shoulder seams are roughly at the top corners of your actual shoulders. From there, the jacket may need to be adjusted by sleeve length, shortened overall, and most importantly, adjusted amidships. Even if you have extra segments around your middle, there is still a need to adjust the jacket. "Taking in" and "letting out" actually mean several things. A tailor or very good seamster can assist you with making certain allowances or snuggings-in at strategic spots. Pinned jackets with half-inch adjustments seem a bit too exact, but they can completely alter the shape of your shadow.

The shoulders and collar fit perfectly off the rack, and Frank and son Bill know exactly how adjust them regardless of the customer's shape. He has a pretty limited selection, but doesn't charge for the tailoring, and the suits are generally at a 40-70% savings. I ask him to put buttons for suspenders in all of the pants, and add a small loop under the backside of the lapel under the buttonhole to hold the stem of a flower.

If you like your jackets skin-tight (I don't), you'll have to argue with the tailor a bit to get it brought in that much. If you like to wear you pants in the high-water position and also skin-tight, your tailor should rightfully give you crap about it. One thing you can tell the tailor or seamster is to "take it in, but leave the fabric". This lets them know that they will see the jacket again after you've plumped up a bit and become ready to ease the sheets and fall off to a comfortable broad reach of caloric indulgence.
Don't fall victim to some of the advice floating out there concerning the purchasing of suits. There is nothing wrong with the inexpensive ones, and while they may not be as elegant or as fine as some of the other pricier models, it is all about the wearer. I see $1000+ suits everyday in Boston, but they are often maladjusted, boring in application, and a dreary waste of fine material. Even a clearance $100 or $200 or thrift-store suit can be FAR more elegant than the $800 or $2000 when you have it altered to fit you well, so don't be intimidated or scared off by the idea of buying a suit. Good clothing is often little more than good fit. If you are not shaken by the more bold patterns, you will have an increased chance of finding a suit at astonishing discount.
One small point though: when you get fitted for a suit or are even just out suit shopping, wear dress shoes and a collared shirt if you want the adjustments to be correct.
