I spent almost an hour trying to decide what size to get?  The size chart provided makes no sense at all because if I would've followed the chart provided I would've been wearing a size "night-gown" and it would've been way too big.  So, here's my input and I hope it helps you ladies out... I wear a size bra 38C and I'm still losing weight from having a baby so sometimes I can wear a medium tank and other times I have to get a large?  I ordered a Large and I was surprised that it was baggy, however, I haven't washed it yet.  I'm going to wash it in cold water and tumble dry low to see what happens?  I'll update after I wash it.
