Vicki, if you don't mind my asking, when you say the top fits like a glove, exactly how close is the fit? Is it:
a) skintight - negative ease on torso and arms (I expect not based on your photo)
b) skintight - 0 ease on torso and arms (ie, it's not stretching out but there isn't any space between the garment and your skin)
c) tightly fitted - very small amount of positive ease on torso and arms (you could wear a swimsuit underneath without it showing through)
d) fitted - small amount of positive ease on torso and arms (you could wear a standard tank underneath without it showing through)
It looks like it's either b) or c) from the photos, but I couldn't be sure. Thanks if you see this! I'm having a hard time figuring out how mine should fit on me.
