Drop (suit / jacket)
The numerical difference between chest and waist measurements in suiting. A 6-drop is a 40-chest with a 34-waist; a 7-drop is more athletic.
In suiting, "drop" is the difference (in inches) between the chest measurement and the waist measurement of a tailored jacket. A "6-drop" 40-jacket has a 40-inch chest and a 34-inch waist. A "7-drop" 40-jacket has a 40-inch chest and a 33-inch waist — narrower waist, more aggressive shape.
The drop reflects the pattern's assumption about your body type:
• 5-drop: looser, more rectangular cut. Common in older / fuller-figured tailoring (Brooks Brothers traditional, Jos. A Bank).
• 6-drop: standard "American cut" historically. Slightly tapered. Default for most off-the-rack suits in the 1980s–1990s.
• 7-drop: more tapered waist, more shape through the body. Default for most modern slim-fit suits.
• 8-drop: aggressive waist suppression. Italian / runway cut. Most off-the-rack 8-drop suits don't fit anyone with normal abdominal proportions; usually requires letting out at the waist.
The practical implication: if you're in shape and hit the chest measurement, a 6-drop will likely need waist alterations. If you're bulkier through the midsection, a 7-drop will be too tight at the waist. Try multiple drops at the same chest size to find the cut that matches your actual proportions.
Most RTW brands publish drop somewhere in their size charts but bury it. Brooks Brothers offers their suits in multiple drops; Suit Supply, Bonobos, and others typically pick one drop and offer it across sizes.
Rise (pants)
The distance from the crotch seam to the top of the waistband. Determines where the pants sit on your body — high, mid, or low.
Break (pants)
How the pant hem sits over the shoe — full break, slight break, no break. Determines the formality of a tailored look.
Full canvas (tailoring)
A jacket construction where the canvas interlining is stitched (not glued) to the wool throughout the front. Drapes naturally, breaks in to your body, lasts decades.
