  • Soft and comfy; beautiful color.
Color: Black L 3 Pack Size: 6-9 Months
These onesies are fantastic. I ordered the black long sleeves. The fabric is thick and soft, and the color is pure. They were a bit long out of the package, but they are 100% cotton, so they shrank up a bit in the wash, mostly lengthwise, without getting much smaller. I got the 6-9 month size, which was perfect for my smallish 7-month-old. Babies above the 50th percentile might need to size up, especially if you want to get a few good months' use out of the shirts. Like other reviewers have stated, they did collect lint/fuzz in the dryer, but it was easy to remove with some packing tape, and it only happened the first time through the laundry. I washed them several times now; there's been no fading or pilling. It's difficult to find basics for babies in solid colors other than white, so I will definitely be ordering more RomperInBox when baby outgrows these, and when the weather changes. Perfect for layering, and quality enough to wear alone. 5 stars! ... show more

  • Perfect. Soft, thick, and good quality.
Color: Black L 3 Pack Size: 3-6 Months
These are the best onesies on Amazon. Thickest and softest. Better than the Gerber ones!

  • Love!
Color: Black L 3 Pack Size: 6-9 Months
My daughter was Raven (from Teen Titans) for Halloween and this was perfect! (Seriously...it was this and a quick homemade cape with hood and the belt...so easy!) She is in her crawling phase now and we went to a friend's house for a Halloween get together. I love that this was a three pack...because babies are messy and this way, we could keep her in costume all night! Now that Halloween is over, these onesies still get plenty of use. We love being able to put her in a color other than pink or white...she's such a classy baby lady! Definitely one of my top favorite purchases I've made as far as baby clothes go! ... show more

  • Pros and Con
Color: Black 5 Pack Size: 12-18 Months
If I could, I’d give this products 3 3/4 stars. There are many pros and one HUGE con. Pros: 1. The colors are true to the pictures and they DO NOT BLEED when washed the first few times, which is great! 2. The price is wonderful for 5 onesies. 3. The material is wonderful. It’s soft and thick but not so thick that your little one will become a pot pocket. 4. The neck is wide so if your little one has a larger head, you won’t have to stress to get their head through. Con: THEY SHRINK, DRASTICALLY! I purchased 12-18 months for my 5 month olds (each are about 25” long and weigh almost 19lbs) thinking that they could grow into them and, after removing them from the dryer, noticed that it will work for them now. So, the 12-18 months shrink to about the size of a garanimals/gerber 9-12 month. I’d buy a size or 2 up for sure. I’ve included a picture to show the size before washing (white) and the size after washing (navy blue). ... show more

  • Great quality!
Color: Black 3 Pack Size: 3-6 Months
It’s a little pricey for plain onesies but now I know why! It’s because of the quality. The fabric is thick and great quality. I used one for a custom onesie with HTV and after pressing the vinyl on it, the vinyl was smooth! No “craters” or bubbling. It was very smooth! I love it!

  • Great value!!
Color: Black L 3 Pack Size: 6-9 Months
These are really great quality, better than expected actually! They’re soft and wash well, don’t really fade either! My only critique is the sleeves are a little short. Granted, my baby is 4 months in 9months size so he’s kind of big but I got the right size and sleeves are still a tad short in comparison to carters brand, same size. I’d buy again though ... show more
