What a cute onesie! It seems like good material and the print is good. I wasn't sure if the 12 months size would be 9-12 months or 12-18 months, but I would say it's 9-12 months--similar to Carter's sizing.So disappointed in this product. The first thing I noticed when opening the package was the smell. It reeks of vinegar for some reason. Secondly, the letters are not bright and vibrant at all as these photos show. They are NOT opaque and you can see black through the color in the lettering. I wanted this to announce to friends and family of my pregnancy but this will be going in the garbage and I will have to find something else. Don't waste your money!!! ButIt was WAY too big!!! We had to throw it away. It wasn't very high quality either.Was a great way to announce pregnancy
