I purchased this bra set because I have some Ahhh bras and use them to sleep or use around the house. I figured these bras would be about the same and they pretty much are but are a bit larger in the cup area. They don't provide support if you're looking to wear them outside the home but are great to sleep in and do housework in. I am also taking these bras to the hospital to wear when I delivery my baby so I won't be all hanging out while I have visitors but I will still be comfortable. I ordered a size medium and I wear mostly medium tops and my bra size ranges from 34-36 DD.
