I'm not sure what is meant by "front panel" or how a coat's waist can be taken in this way. Most coats are made one of two ways: either from four main pieces, or six. Â (I'm talking about the body only, nothing else.) Â The back is nearly always two pieces, joined by a long seam in the center. Â The outside edges are in the back. Â The fronts are either one piece for each side, reaching all the way around your side to reach the back pieces, or there is a seaparate side panel, maybe 8" wide, that runs at the bottom from the rear side seam (or vent) to the front. Â Coat's made like this typically look like the rear dart runs all the way to the bottom of the coat. Â Except it's not a dart; it's the seam of panel that runs from the armhole to the bottom. Anyway, you can adust this seam to increase waist suppression, but it's harder to get right. Â Most tailors will use the center backseam or the rear side seams.
