with out bulkness? I bought a light tan v-neck carg. and I wanted to wear a striped collar shirt underneath but the button up shirt is to heavy and it creates bulk. Should I get a size up in the carg.or go with thinner shirts? maybe just wear a shirt without a collar? Are there lightweight button ups? Here is a pic of the carg, much cuter IRL . I thinking about exchanging it for a size bigger anyway because the buttons at the bottom tend to bulge open a little
