Best Undershirts for Baby Girls of 2025

"I bought these for my 7-month-old daughter. The pictures and description are accurate, and I'm very pleased with my purchase. The material feels like cotton but stretches like spandex. I love the colors and designs. There was a slight smell from dye, so I recommend washing them before use. They didn't shrink when washed, and I always choose a size bigger just in case. Overall, I'm happy with this purchase and may order again in the future. Great price as well!"

"I got these shirts for my granddaughter when she started potty training, as the onesie tees were too long. They are perfect! The material is soft and well-made, and they get even softer after washing. I love that they start closer to her neck, keeping her warm during cold winter nights."

"I ordered these to sublimate, and I must say, the design came out nice. My clients love them!"

"I absolutely love these shirts! The material is just right—not too thick or too thin, and it's super soft. They also resist stains surprisingly well, which is a huge plus since they last longer. My only issue is that they are a bit short over my baby's belly, but they are a fantastic alternative to onesies for daycare. It's much easier for the staff to just remove the pants during diaper changes. The sleeves fit perfectly, and the neck is a good size for my baby's head. I would definitely recommend these!"

"I bought these shirts for my daughter, expecting them to be a little big since she's only 10 months old. To my surprise, they fit her just right, maybe even a little snug because she’s a big baby. They're very stretchy and seem comfy, but I did notice a weird smell, and they are slightly see-through. Overall, though, they are perfect and worth every penny!"

"I have been using these shirts for years, first for my son and now for my daughter. They work great as sleep shirts but are versatile enough for any occasion. The extra stretch and the flaps near the shoulders make it easy to take off if there's a mess, without spreading it everywhere. The material is thicker than typical shirts, making them ideal for little ones. I love the bold colors that match with almost anything. I highly recommend these!"

“I absolutely love these undershirts! They are super soft and fit my average-sized 2-year-old perfectly when I ordered a size up (3T). They wash well and are long enough without being baggy. I highly recommend them! Update: Although they remain comfy, I've noticed they might be shrinking a bit, so I plan to order a size or two up.”

“I purchased these for my granddaughters to wear at home. At 3 years old, they love being comfortable in shorts and a t-shirt. These shirts are also perfect as undershirts under long sleeves. I appreciate that they don't shrink in the dryer, and I would recommend them to any parent looking for quality t-shirts.”

“I was thrilled to find these shirts since I had difficulty finding t-shirts at local stores. The price was fantastic—I paid about the same for 6 shirts compared to $18 for just 2 at Carters. They’re just what I needed, and I might even order another set soon!”

"I found these fantastic little camisoles when my daughter was born 7 months ago. I appreciate that they are made from 100% high-quality cotton and are very well constructed. We've used them daily, and the snaps have held up well while being easy to use. They fit perfectly around her legs, providing enough coverage for her to feel comfortable and warm. Just a note on sizing: my daughter is in the 50th percentile for length, and the sizes fit as expected."

"I really liked these tanks for my daughter, but I noticed they run a little small. I bought the 9-month size since that’s what she was wearing, but they fit quite tightly. The cotton is nice and soft, and the snaps are sturdy. Overall, I would definitely recommend them to others."

"I ordered a size up because I heard they might be small. My daughter is tall, and I was surprised they were still a bit short on her, but they fit well in width. The material has been durable and held up nicely. Overall, I'm pleased with the great quality."

"I love the softness and comfort of these tank tops. They fit my 3-year-old perfectly and are form-fitting and stretchy, making them ideal for her skirts. I was pleasantly surprised by their thickness and overall quality. I would definitely recommend them!"

"I was thrilled to find these undershirts for my petite 9-year-old. They fit her well under the arms, and the shoulder stays in place. The length is perfect for tucking in, keeping her warm and looking modest. I plan to buy again until she outgrows them!"

"These shirts are great! The 5/6 size runs true, and my daughter absolutely loves the bow detail. The elastic straps help with stretch, making them a favorite in our household."

"I find these tshirts to be very comfortable and durable. My daughter loves wearing them!"

"These shirts are stylish and perfect for layering under clothes. I'm so glad we found them!"

"This is our second set of the undershirt & undies for my daughter, who runs warm and loves sleeping in them. The first set I got when she was 3 years old in size 5 looked big initially but shrunk after the first wash. Great quality, stretchy, and soft! It fit her from ages 3 to 6. Now at 6 1/2, I ordered a size 8, and they fit nicely, likely lasting her a year or two. Definitely worth buying! Just size up 2 sizes!"

"I ordered toddler underwear in size 5 and was pleased with the quick delivery and nice packaging. The quality of the material is impressive, but I found the sizing to run small. I reordered a larger size and will gift the original order since I want to ensure a perfect fit. Keep the sizing in mind when you order!"

"These are wonderfully soft for my 2-year-old. I've bought them in 2T and 3T, but they do run small and can feel a bit tight around the armpits since they don't adjust. If your child is petite, the regular age size should fit, but for average or tall kids, definitely size up!"

"I find these undershirts super soft and the perfect size! My daughter absolutely loves them, especially since they can be worn not just as undershirts."

"These are definitely good quality undershirts. My 5-year-old is 3'7" and 36 lbs, and I bought size 6/6X/Small. I went by her weight instead of measurements, which I’m glad I did, as a smaller size would have been too tight. After washing, there was some shrinkage, but they still fit well and look sturdy."

"I really like how this undershirt tank top fits. It’s made of 100% cotton, not too thin, and sits nicely under dresses or shirts. The little bow is such a cute touch!"

“My 10-year-old daughter is always cold, so I bought these for extra warmth. She adores them and finds them very comfy. They are holding up well so far.”

“I find these shirts adorable! My daughters wear them under jumpers and strappy dresses. They do run a little small, but still fit well for layering. I’d suggest ordering a size up.”

“The fit is perfect! The material is of good quality and maintains its shape even after washing. I only wish they offered more than two per pack.”

"I bought this for my 4-year-old daughter to layer under clothes for winter. She wears a 4T in most sizes, and the 4-5T fits perfectly. The length is nice, covering her waist, and the sleeves are long enough. It's a bit on the thin side, but that's great for layering, and the bow adds a cute touch. Overall, for the price, it's perfect for a season of wear."

"I absolutely adore these t-shirts! They are incredibly soft and well-made. The scalloped edging and little bow around the neckline were a delightful surprise that I couldn't see in the online photo. I will definitely be purchasing more from the Carter's line for my daughter in the future!"

"These undershirts are just what I needed. They are soft and have long sleeves, making them perfect for winter. I had a hard time finding these in stores, and I love that they don't snap at the crotch. My granddaughter will be nice and warm this winter, and I plan to order more soon!"
