For size references I was a 34C pre pregnancy and I am currently a 36C 1 month post partum. I am 5'10" and weigh 165 pounds. I purchased a large and it fits perfectly.I must have bought somewhere over 30 nursing bras to try from amazon, nordstrom, and motherhood maternity combined. And all of them sucked. What I don't understand is why companies think that nursing women won't mind their nipples showing or poking through their nursing bra and shirt! Maybe women who use nursing pads don't have this problem, but if you don't use nursing pads the nipple poking through is unavoidable. The sewn in soft cup solves this problem. This was the only nursing bra I was able to find that doesn't have this problem and is comfortable to wear.It's only drawback is that it is a pullover style bra and it is on the pricey side however, it has held up well in the wash and it's constructed well so it seems like it will last me a long time.I currently use this as my daytime bra and wear a Heidi Klum nursing bralette at night to sleep in to prolong the life of my Cosabella bra. I also reccomend the jessica simpson nursing camis, they have a built in bra that also prevents the nipple issue.Pre-baby, I almost always wore their never say never bralettes so I figured this would be great. It’s nicer looking than some of my other nursing bras, but a bit too tight and I actually think not having a clasp makes it more inconvenient (where I usually liked that feature about their non-nursing bras).One of my favorite nursing bras. While it’s a bit pricey, I still prefer it over other lower priced options. It’s hard work nursing your baby, why not treat yourself a little so you feel good about what you’re wearing. As for sizing, I’d definitely recommend sizing up. I’m a 32 C pre-pregnancy and currently wear a large.Pros: comfortable and stylist. Easy to unhook for nursing.Cons: lace will look lumpy under thin t shirts. Runs small.Best nursing bra. Somewhat supportive and if you forget to hook it back it holds your boob in place somewhat- the stretchy unlined ones tend to fold down under your boob. Also if you're using those nursing pads, they're completely visible under most popular nursing bras. This bra is supportive without underwire, and had enough shape to hide a bulky nursing pad. Plus if you do leak it won't go through to your shirt instantly. ALSO the hook is in a place that is easy to get to when you already have your shirt hiked up, as opposed to all the way practically to your shoulder like some of the others. I didn't think of it when I was pregnant but it's difficult to reach your hand under a shirt and then bring it back up your shoulder to hook your bra closed (or dig down the collar of your shirt). Either way, this one is right there when you're done nursing. Great bra. Only drawback? It's not cotton!!Fits a little small. I used the sizing chart. I did purchase a second one. Maybe the first one was made a little smaller. It happens. Other than the tightness. It is comfortable and definitely makes you feel like a lady again even tho it is a nursing bra. They are a little pricey. I do wish you could adjust the back like a good bra. These are pull over. I feel for the price you should be able to adjust the bra to fit you.I measured a 36C (pre-birth) and so I ordered a Large because a proper sizing chart was not provided and many of my camis are M/L. The material for this product is not very stretchy and barely fit (as a 36C). I thought the quality and look was fabulous and that is why I will be exchanging it for a larger size. I just wish I had a better reference for sizing before ordering. I hope this helps other women decide on what size is best for them.Too small for me as I am a 32L currently pregnant. But very high quality and would fit normal chest sized women well I think. Sad it didn’t fit.Scratchy!! Was expecting a soft lace, this is rough. Haven't even worn it :-(I use this bra as a sleep bra. It's so soft and comfortable that I don't mind wearing it to bed, which is something I used to hate. The reason I chose it as a sleep bra is because the size on me feels like it fits just a bit large and it doesn't give the support I'd like during the day. However, I love it for night. The lace is not scratchy like I feared. And bonus, it's just a gorgeous piece of clothing that happens to be handy for nursing!Mi dicono vada beneWould be nice if there was an opening in the back.
