Before we explain what a "separates program" means, it may be a good idea to explain a "nested size scale". A nested size scale usually comes in what's called a "6-inch drop". This means that the pants come in a size that is 6 inches less than the jacket. For example, if a nested suit has a 40R jacket, the pants would automatically come with a 34 waist. If the gentleman wearing the tuxedo actually has a 33 waist, he would require his local tailor to take the pants in and make the 34 waist into a 33 waist.The desired feature about a "separates program" is that you can order any size pants with any size jacket. Using the example above, the same gentleman could order a 33 waist pants with his 40R jacket if the program is a "separates program".A large percentage of the tuxedos that we offer are available in a separates program; this makes things easier for sizing.
