This is so much better than the other models I tried with my first pregnancy.  It is sturdy enough that it doesnt need the halter, and washes well.  I am a 38D and for the first two months after having the baby I used the L/XL and now use the S/M.  I don't know in what other product I could ever use a S/M... but definitely it works now for me and I am a size 14.  It is very adjustable, which is great.  I just wish the holes on the S/M were as large as they were on the L/Xl.
