Two Brands To Choose From
We offer two different brands to make sure you get exactly what you want! Details on both our Carter’s and Gerber Onesies® are outlined below. Unless otherwise indicated, all onesies are white with short sleeves.
The Carter’s bodysuit is made with 100% cotton rib fabric for maximum baby comfort and softness that also lends to an excellent print quality and durable onesie for your baby. Onesie features include: expandable shoulder neckline for easy dressing and emergency blowouts and reinforced triple button snap closure for easy changing.
The Carter’s sizing chart is below. Due to the potential of slight shrinkage on first wash and your baby’s growth, we recommend if you are unsure or close to the weight/height thresholds that you ORDER ONE SIZE BIGGER than the size you think you’ll need.
We sell the following sizes:
Newborn - 6-9 Ibs. / 18-21.5 in.
3M - 9 -12.5 lbs. / 21.5-24 in.
6M - 12.5-17 lbs. / 24-27 in.
9M - 17-21 lbs. / 27-28.5 in.
12M - 21-25 lbs. / 28.5-30 in.
18M - 25-28 lbs. / 30-32 in.
24M (2T) - 28-30 lbs / 32-34 in.
To properly care for your Onesie machine wash the onesie inside out with cold water on a delicate cycle. To dry, tumble dry on a low heat or hang to dry. Do NOT use harsh detergents, fabric softener or bleach. Do NOT iron.
The Gerber Onesie® is made with 100% cotton rib fabric for maximum baby comfort and softness that also lends to an excellent print quality and durable onesie for your baby. Onesie features include: expandable lap shoulder neckline for easy dressing and emergency blowouts, double button snap closure for easy changing, and a ribbed leg opening.
Gerber Onesies® tend to run a bit small and can shrink some on the first washing. Your baby will also inevitably grow! Thus, we recommend if you are unsure or close to the weight/height thresholds that you ORDER ONE SIZE BIGGER than the size you think you’ll need.

Newborn - 5-8 Ibs. / 17-21 in.
0-3 months - 8 -12 lbs. / 21-24 in.
3-6 months - 12-16 lbs. / 24-26 in.

All of our onesies are printed with love on a world-class direct-to-garment printer that offers a far better print quality than vinyl heat transfer. The eco-friendly inks used are kid and pet safe and have been rated with the highest rating for the number of times they can be rewashed before fading occurs. Post-printing we cure the ink with a commercial quality heat press to ensure your printed onesie does not crack. We are 100% confident you’ll love the gorgeous and long-lasting onesie that you will get. Please note, white ink in any design does not print. Rather, any white elements in the design will use the white of the onesie.
