I bought this bra after my baby.  I was breastfeeding and I went from a 36DD t 36 E/F.  I needed something with good support.  I got this in a 36DD..It was pretty snug at first (due to my engorgement) but it kept the girls in place.  As i lost weight I was able to adjust it and still get great support.  I LOVE the adjustable straps on the shoulder.  The 36DD still offers amazing support but I am going to get a 34DD now that I am done breastfeeding and lost most of my weight.
