In this case, the issue seems to be the wrong fit. The bra will slip only if your band measurement is too big and possible the cup is too small. You might want to try size 30F or 30FF and that should offer your more support. Style 3370 is a great strapless, but you have to be in the right size to experience real benefit of this style.

Also (again, this might be due somehow to the one I tried being too small in the cup for me), it seemed to point me left and right, while flattening me out in the middle. I would rather have my breasts centered up front and outwards, than flattened and going out to the sides.
HerRoom Response: Thank you for your feedback. We have forwarded your comments to Panache.
Panache Strapless style 3370 tends to run a bit shallow in the cup in general, so since the customer is already a G cup, I'm afraid this particular strapless may not be the right fit. I would however recommend our new Strapless Evie style 5320 as that style goes up to H cup and I think would be the best fit, but I would recommend trying both GG and H cups in this case. As far as other silhouettes go, if she liked style 4031 Harmony Balconnette, I suggest she try Confetti Bra style 4071, those two bras are same shape, she might also want to try style 3256 Tango Plunge. In the last style, I would suggest going up to GG cup.

HerRoom Response: The symptom you describe many times happens when a woman has implants because the shape of the breast is rounder. We do not know if this is your situation. Panache may simply not be your brand.

"Due to the molded plunge construction of this strapless bra, the cup sometimes may appear to fit a bit shallower, so we recommend customers go up a cup size in this style"

HerRoom Response: A strapless bra is the ultimate test of your bra size. Unlike a traditional bra, you really need to know your exact size if it is going to fit. If you think this bra was huge, chances are your band size could be smaller as well as your cup size.
