My daughter was turning 30 and having a dirty 30 birthday themed party.  She has seen many of my cakes and asked me if I could do her a boostia cake for her 30 party.  I made the bodis with a sheet cake with the curves cut out on each side.  I made the beasts with a round half pan.  I used only buttercreme frosting on the cake.  She asked if I could put a tattoo on one of the breasts with her husbands name in it.  You can barely see it on the top of the right breast but it is there.  The cake was a great hit and I got orders from the party for others.
