My question is about the fit of these two vests. I love them but am worried they may be a bit too big. To the experts: please see what you think. To get them to fit the way I like, I have to pull the belt in the back as tightly as you see in the photographs. Questions: 1. Are the vests too big, thus requiring me to tighten the back too much? Or, is this bunching proper and to be expected. 2. If so, by how much should the vest measurements be altered? How much do they need to be taken in? In the waist or the chest? 3. Is this an alteration that can be done? (The vests have are undarted.) Grazie mille, Z pics 1. 2.
