I bought the Dream Tisha Lace, Dream Tisha, and Tisha bras.  I expected them all to fit similarly, but they did not.  Here is my comparison:

Tisha -- 2 hooks in back.  Unlike Dream Tisha lace, cups did not keep their shape for me.  Fits smaller than Dream Tisha and Dream Tisha lace.  Works better than Dream Tisha or Dream Tisha Lace for lower cut tops.  I kept 1 of these bras for lower cut tops, but the lack of cup smoothness is a problem.

Dream Tisha -- 3 hooks in the back. Straps are wider than Tisha.  Cups were flimsy and creased when I wore them.  Looked terrible on me.  I returned this bra.

Dream Tisha Lace -- 3 hooks in the back. Straps are wider than Tisha. Nice and supportive for my 36D frame. Molded cups held their shape on me.  Perfect fit for me.  Only problem is that the lace comes up high enough to be seen with some tops.  I will buy enough to wear this bra almost all the time.
