Girls Briefs 5 Pack and Tank 2 Pack

I purchased the Girls Briefs 5 pack and Tank 2 pack for my daughters and couldn’t be more pleased. Upon opening I immediately noticed the silky soft touch of the organic cotton which I have not found in any of the most known brands today for children’s organic cotton clothing. The soft hue prints and colors tones are inviting and make getting dressed fun! The pattern cut of the briefs provides appropriate coverage. All the items run true to size with allowing room to grow. The flat seams are perfected and make the clothing sensory friendly. No more complaints from my children mentioning that the items are “too tight” or “too itchy” but now instead I am hearing “these are the comfiest undies!” and “These tank tops are so soft, Mama!” Also, a huge win when speaking of how the items washed as they kept their shape and softness! If you haven’t found the essentials that truly work for your child then I highly recommend trying Treehouse! We couldn’t be more thankful for their GOTS certified organic collections so carefully thought out and ethically crafted!

We love how versatile these tanks are. We can use them for everyday wear and they are also comfy enough to pair with pjs for a good night’s sleep!

100% cotton tank tops

It is so hard to find 100% cotton tank tops these days. My kid has eczema so sensitive to cotton-poly mixes when flush against their torso; so finding these for layering has been super helpful.

So very pleased to hear this feedback from an eczema parent. This was precisely my driver in starting Treehouse. Thank you for sharing your feedback!

Comfort and versatility

I’m so impressed with these tank tops! The fabric is organic and incredibly soft, making them super comfortable for my kid to wear all day. They’re versatile enough to use as layering pieces or on their own, and they look great no matter how they’re styled. I also appreciate that they fit true to size, which makes shopping so much easier. Overall, these have quickly become a staple in my kid’s wardrobe!

So glad to hear this! We also recommend mixing and matching these with the PJ bottoms!

The cutest prints on the softest fabric!

So soft, so comfy! My little lives in hers! I do suggest sizing down for a regular snug fit. We purchased the size for her age and it is slightly oversized but it’s for bedtime so it still works for us! It only means she will get to wear it longer!

Thank you so much for your feedback! And great guidance on the sizing!!!
