Pretty good, glad I sized up
Wasn't sure about ordering a size up but glad I did, it fits way better. The organic cotton actually feels really good against the skin, not itchy at all.

So comfy, love it!
OMG, literally perfect tee.
Perfect gift for a science enthusiast!
My boyfriend is a huge science nerd and this was the perfect gift. He wears it all the time and says it's super soft.
My new favorite tee, second one from them!
This is actually my second tee from Design Delight Studio, and honestly, the quality just blows me away every time. I wore my first one until it literally fell apart (after like 3 years!), and this new 'Proton' design is just as good, maybe even softer. It's awesome knowing it's organic and ethical too; makes me feel pretty good wearing it, not just comfy. The fit is solid, but yeah, definitely size up if you're in the US!
