I have tried several styles/brands of the "wear your own bra" type of briefer and this is the most comfortable so far.  It says "firm control" but others I've tried are much firmer, and this one seems like a "medium control" to me.  It doesn't have the hard shaping that some garments do and is kind of like a leotard with a lot of control.  The shoulder straps take some getting used to and they did bother me at first.  I have worn garments like this before and they all have that problem.  After a while the straps squish up and won't stay flat and that is really the only reason I have not given it 5 stars.  It makes my clothes fit much better and takes care of the "muffin top" pretty well.  I have a short rise and it may be a little long for me, but it works.  I ordered the Medium, I am 5'6", 150 lbs. and it fits perfectly tightly.
