This bra is incredibly beautiful, but way too big for me. I put it on overtop of my 65GG - Ewa Michalak » Ch Purple (223) and there is still empty space in the cup, so would probably be a better fit for someone who wears a ~28J.
The band is firm, fastens with 3 hooks, and feels comfortable to me on the loosest hook.
Oh how I wished this fit. This is the "F model" that Avocado calls a demicup. It is very lightly padded (less so than EM or Comexim) with a lower neckline than the K models. The underwires are a touch wider than the K model as well but not so much that I get empty space on the sides.
I find all of the Avocado bras I've ordered (4 at this point) are nicer in person than they photograph. There are lovely little touches that overall give a more luxurious feeling and for my particular shape, the fit can't be beat.
