IMJ's most-requested style is back — and it just got a coastal upgrade. Little Coastal Notes scatters vintage-inspired postage stamps across a soft pink base, each one carrying its own little piece of the coast: a pink crab, a blue seashell, and a cluster of blue hydrangeas with coastal motifs tucked in between. Now in a new fabric that's just as soft, just as cute, and ready to travel.

It means peace of mind. Every piece of our clothing is certified by STANDARD 100 by OEKO-TEX®, which is a fancy way of saying:
no harmful chemicals, no toxins, nothing icky- just safe, gentle fabric for your little one.
Oeko-Tex testing goes above and beyond national safety standards. From the thread to the dye, everything is screened for over 100 harmful substances. If it touches your baby’s skin, it has to pass the test.
You get softness they love, with the safety you can trust.

Because softness matters- especially at 2 a.m. Our pajamas are made with viscose from bamboo, a fabric loved for its buttery feel, breathability, and natural stretch. It keeps your little one cool when it’s warm and cozy when it’s chilly, making it just right for sensitive skin (and sleepy snuggles).
Plus, it holds up wash after wash, because we know laundry day is always just around the corner.

Yes! IMJ fits true to size- no need to size up.
Compared to other viscose-from-bamboo brands, our pajamas are designed with a comfy, flexible fit that grows with your little one (thanks to the natural stretch). If you’re familiar with other bamboo brands, you’ll find our sizing refreshingly consistent- snug, not tight; roomy, not baggy.
When in doubt, check our size chart or reach out- we’re happy to help!

Customers say these pajamas are incredibly soft and adorable, featuring cute prints and thoughtful design details like ruffled shorts and button-up tops. Many praise the quality and comfort, with children wearing them repeatedly. The matching mommy-and-me styles are popular for photos and special occasions. Some note the bottoms run small, so sizing up is recommended for the best fit.

My daughter loves her pajamas! More in size 11/12, please!
- Emma K.Verified BuyerReviewingIndie Floral Button Up Short SetI recommend this productRated 5 out of 5 stars3 weeks agoPerfect - so pretty!
We bought these for my daughter and she insisted on buying them for her bestie too so they could have a sleepover together. They're just perfect!
- Emma K.Verified BuyerReviewingFloral Seashell Button Up Short SetI recommend this productRated 5 out of 5 stars3 weeks agoSo soft and comfy
My daughter is living in these! Unfortunately, she wasn't a fan of the frill along the bottom so I had it removed to just have a straight edge hem. Perhaps this could be a suggested option for the next design. (Personally, I adore the frill - kids!).
- Taylor H.Verified BuyerReviewingShoreline Dreams Button Up Short SetI do not recommend this productRated 1 out of 5 stars1 month agoNot the same fabric
I have ordered tons of pajamas from IMJ in the past and have always been very happy with them. Unfortunately, that is not at all the case with these. I am very upset to find out upon arrival that they have changed this style to polyester material. It was not advertised anywhere that the fabric was no longer in fact bamboo. There’s no way I would have paid so much for polyester pajamas that are not breathable at all. Please bring back bamboo for this style and be more upfront about changes. This was very deceptive.
