Harper H. ★★★★★ Oct 18, 2026

The vertical pleats on the shoulders add such a subtle, elegant detail that makes this tee feel more polished than your basic long sleeve. The regenerative cotton jersey is soft but holds its shape well after a few washes.

Avery ★★★★★ Oct 14, 2026

I've worn this tee three days straight since it arrived and it hasn't stretched out at all, which is rare for cotton. The regenerative cotton jersey feels denser than my old basics, and the shoulder pleats actually add a nice bit of structure.

Ava ★★★★★ Oct 13, 2026

The vertical pleats on the shoulders give it a little something extra without being loud, and the regenerative cotton feels substantial but not heavy. Fit is true to size and it washed up without shrinking.
