I disagree with J, a little. Â "Roll" is usually used to refer to the length of a lapel. Â Remember that a lapel is simply part of the front of a coat, turned back and as it were "doubled up" over the chest. Â But the whole front is not turned back, only the top part. Â That top part is the lapel. Â It begins at the collar, and extends down to the middle of the coat. Â It is said to be "rolled" to wherever it ends. Â Thus on a standard two-button suit, the lapels are rolled to the top or waist button. Â On a barbarshop quartet-style 3-button suit, they are rolled higher, above the third button. The phenomenon J describes -- a graceful flare away from the body that curves gently back toward the chest of the coat at the lapel's edge, resulting in a kind of bulbousness and spring -- is more properly termed "belly". Â Lapels with no belly at all, that are pressed completely flat against the chest, are easy to make, but unattractive, in my opinion.
