Gratias dicamus Domino qui Diedram ornavit pulcherrimo corpore
(Always presuming that the owner of this wonderful bottom is feminini generis, otherwise it should be Diedrum) = let us say thank to the Lord who ornated Diedre with a most beautiful body. If you insist on the bottom, scratch corpore, put anu (but that doesn't sound well).
On second thought: ... ornavit pulcherrimis globulis = with most beautiful roundings.
You may be assured that this sentence is the first grammatically correct contribution.
