The 0-3 mo size fit my 5 week old really well but on the tag it says 3 months. I put a white short sleeve onesie underneath as the inside of the dress was not comfortable because of the type of fabric and the seams and seemed like it would be itchy. It showed a little bit under her armpits but didn't look bad. The dress is really cute and great for a baby dress since they don't wear them for very long anyway, but it's not amazing quality. I loved it for my event though and she's worn it a couple of times since.Had a very hard time finding a baptism dress for my preemie daughter who is a little over 7 lbs and this dress fit well. It helped that the bust measurements were provided so I wasnt guessing. It was a little big on her but I was happy for it being a 0 to 3 month dress since we couldn't find any in newborn sizes. We put a white onsie tank under it since it doesnt have a diaper cover and the material isnt very soft. Overall worked perfect for what we needed.An adorable dress. Roses we're not as pronounced as they looked in the picture.Really cute dress but runs small I ordered a 6 months and it was more like 3 monthsPretty design & the layers aren’t thin.When placing my baby down I noticed there was hard plastic sticking out of the skirt of the dress. After investigating it, some there was multiples. These could have poked my daughter and/or causes her harm and I wouldn't have knownCute dress but the material is not baby friendly.. very rough so baby won’t feel comfortable in it for too longBeautiful dress and perfect for our daughter’s Baptism.
