Sara, yeah, if I love the dress, it may be worth adding the snap. I may wear a cami anyway.
ophelia, I hear you - our clothes should not be so fussy! I will put up with it this case because the dress makes me soooo happy, and because the fixes are relatively simple. I actually would use a demi cami, like the one in this Find (not this color though). That solves the bunching problem.
I will add that I don't think the design is flawed per se, except for those who don't like a deep vee; whether I want to show that much cleavage will depend on where I'm wearing it. People's comfort levels vary on that topic! I'm just smaller on top than on the bottom, so there's more gapping than an hourglass figure might have, and it's not uncommon for me to have to alter the top of a dress because I'm pear shaped, and short-waisted to boot. ETA: That said, I agree that it would be better if a wrap style top or dress came with the two sides sewn together (unless it's a true wrap, which this is not).
Angie - I happened to be wearing a different combat boots when I tried it on. Perfect 90's synergy.
