Draft without a sidebody

Thank you! I much prefer the look of a one-piece front, but I’m wondering if there’s an advantage to the sidebody or just personal preference.

@Philip De Paola I've heard tailors argue that the seam of a side piece helps shape the material better at the sides, for a fitted look. Three-seamers/sack coats are usually a little roomier/boxier/more relaxed looking. Personally, I prefer that softer look.
