Avirosemail,
On my one RS tour there was a woman who wore Columbia vests(s). She had two similar vests, but I think different makers. One was black and one was ecru. She was thin/smallish chest. With the black one, adding a scarf would dress it up. For me, the upper chest pocket would not be too noticeable, but as I have breasts, I attempt to avoid all pockets on the chest. I also prefer some type of dart or princess seam to give them some shape...hard to find, but they show up periodically. I don't buy vests for their pockets, but don't mind when they have side seam zippered pockets because then there is a gap of material inside that will hold a small sack of valuables pinned, should the need arise. I often use the gap for my second pair of glasses...sun versus regular.
That being said, here is a sample of my vest solutions: 1. I have a Costco puffy vest per the recommendations of over one year ago on here. I keep it in my motherlode Jr for my weekly travels. I've not yet used it for my weekly travels, but did use it for an autumn trip to the beach a year ago. It takes up so little room, why not? It doesn't look bad, really, but it is quite informal. I have the lavender grayish one. 2. I have a couple of Landsend Marinac vests. One older, which I loved. One newer that really hasn't been used much due to C-19. (Looks like the newer one has not great reviews...I love the older one, but I like the newer one because it is longer). They both dress up fairly well with scarves...in my opinion (not opera dress, but with accessories a nice restaurant, etc. IMO). 3. The third type of vest is harder to find. These would be tailored and made out of a nice material. My go to is a reversible, princess seamed older vest from Chico's...maybe 10 years? (I hate shopping.) It is nice fabric, thinly quilted, collared. It is my go to travel vest, particularly as part of my plane outfit. Navy on one side and a lighter white, ecru, navy print on the other. I receive lots of compliments on the print side, which I rarely use because I am a plain clothes person and like to blend most of the time...
I think vests make most people think of skiing or multi pocketed travel. I just wanted to point out a few of the other possibilities. And, my plane outfit vest got me upgraded, IMO, a few years ago.
