Favorite shirt in my closet
This is my third purchase from this shop, and they never miss. The vintage-style print is subtle enough for work, but the organic cotton is so comfy I basically live in it at home. My cat actually clawed at the sleeve yesterday and it held up perfectly, no snags at all.
Super soft cotton
I saw this on TikTok and had to grab it. It feels like a cloud against the skin and the print hasn't faded after three washes. Definitely worth the money.
Wasn't sure
I was skeptical about paying this much for a basic tee, but the material is legit high quality. It’s not thin or see-through like most graphic shirts. I’m actually happy I pulled the trigger on this.
So cool.
Honestly my new favorite shirt.
Cute but sizing is weird
I got this for my boyfriend and the design is sick, but it runs a bit small in the shoulders. He’s usually a large but could have used an XL for a better fit.
Decent quality
The fabric is nice, but shipping took forever to get to my place. It’s pretty good otherwise.
