Natori Response: Hello Nicole. I'm the Southwest Area Rep. for Natori. It has been my experience in fitting this bra that if the cup is either too big or too small you may get some rolling due to the soft hand of the fabric and the cup (which is meant for comfort), it sounds like you may actually need a 34DDD in this bra because your full breast tissue may be pushing the top of the cup forward, causing it to roll; (you also mentioned that you're not getting enough coverage and this is a FULL coverage bra) again I would suggest a larger cup in this specific style. I personally wear this bra and it is one of my favs and literally disappears under even the tightest white t-shirt. Nicole from Sarasota, FL
HerRoom Response: Thank you for your kind feedback. We receive exactly the same product from Natori that every other Natori retailer receives. There should be no difference in sizing.
HerRoom Response: Your symptoms suggest that the cup size is too small. Also, when you try on this bra, make sure your back is pulled down so that it is horizontal with the front of the bra. This should reduce the sling look.
