  • Pros and Con
Color: Black Short Sleeve 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

  • No longer my favorite onesies.
I bought these onesies in black a while back and LOVED them. However I recently ordered navy and white packs and the fabric is not nearly as great of quality. A lot thinner, not worth the price in my opinion. Seem to get stretched out faster. Not sure if the fabric changed or the black is just a different thickness but the white and navy aren’t great. ... show more

  • Soft and comfy; beautiful color.
Color: Black Long Sleeve 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

Color: Black Short Sleeve 5 Pack Size: 18-24 Months
Bought the 18month-24month (largest size) for my 14 month year old boy thinking he has plenty of room to grow into. I washed these in a regular cold cycle and regular drying and they shrunk to where they barely fit on him along with the arms are not long sleeve they shrunk to mid arm... these have great material it's to bad and disappointing they are way too small. ... show more

  • Great value!!
Color: Black Long Sleeve 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

  • Great quality!
Color: Black Short Sleeve 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!

  • Very nice quality - a little smaller than expected
Color: Black Long Sleeve 3 Pack Size: 12-18 Months
The quality on these is really very nice. Thick and seem like they'll hold up well. I bought the 18 month size for my 8 month old who's in the 90th percentiles for height and weight. She wears 12 mo clothing and it fits nicely. These 18 month sizes have a little room to grow, but seem a little smaller than I expected. I will probably buy more from this company as she grows, but size up yet one more size. ... show more

  • LOVE THESE!
Color: Black Short Sleeve 5 Pack Size: 18-24 Months
These are very nice onesies!!! They're really well made. I did size up, my daughter is about 22-23 pounds & i Bought the 18-24 months because i didn't know if they'd shrink & even If they were a little bit she'd have room to grow in them but they fit really good! There's definitely a little wiggle room but they're really nice quality & they Fit her perfectly! Really impressed!!! ... show more
