Compared to my other Ewa bra, I would suggest actually sizing down a back size. Maybe up a cup size or the same cup size. I usually wear my bras on the last set of hooks for the first few months, this one needs to be worn on the innermost or the second hook for me. This bra shape is also almost corset like in its effect. I feel like I have victorian era boob. It looks nice with some tops, however it can be a bit awkward looking for a tight fitting tank. I will say it's a nice solid cup material that doesn't seem like it will flop and lose its form.
So after trying this one on a few times, I think I need to exchange it for either a 60GG or 60H. I haven't decided yet because of monthly fluctuations in size. Basically, the bra was too loose for me. It would fall down and dig into my ribs unless I wore it on the tightest hook. I found myself having to arrange myself in the cups and it seemed like it sometimes fit, while other times, I was spilling over.
On a positive note, the cups are made of a very stiff material that actually supported the weight of my breasts (unlike the Deco Strapless, where the bottom of the cup folded over after use). It also looks fantastic in profile.
This one was disappointment for me. I have read great reviews on this model, so i wanted to try how it works. But when the parcel has arrived i was disappointed. The 30 band is deffinitely too loose for me, im on the narrowest hooks and i can still put at least 4 fingers between the band and my ribcage. I would probably send i back, but the cups are some kind of flat, so maybe, they culd be too small. And as the 28 bands cant be sent back i ve change my mind and give this bra one more chance. After an hour walking in the city, it seems that it wont fall down, but i still have the feeling, that it could. Ill write an longer review after more few more experiences.
