I have recently purchased two new suits, a Brooks Brothers Fitzgerald during the summer sale and a Jos A Bank tailored fit (I know, I know, but I was looking for something in the specific color/pattern and it was 90+% off). Both suits tend to fit me snugly off the rack, and in fact, I purchased them a size smaller than I have always previously bought. While both seem to fit well in every other regard, there is virtually no suppression at the waist, as if the jackets are wrapped around a perfectly round cylinder instead of a human torso.
Are there any alterations that would give a more suppressed waist look, presuming that the jacket isn't actually too large in that area? Is the unflattering silhouette just a result of my figure (I'm very thin, with virtually no musculature in the chest), or is it more caused by the boxier cuts of the jackets?
