I bought the Jade tunic tee in Tencel with Pacific Heather originally, and while I liked it I wanted a more saturated color. I exchanged it for this lovely olive tree green (no tencel) in the same size, and I am keeping it. I might dye it still--to get it to be a more vibrant, mossier green rather than the paler light yellow tones of this shade--but I'm not certain if I want or need to. While moss will go better with some colors (looking specifically at Beetroot!), this shade is lovely with Redwood and Plum as is, and it does not go badly with anything I've tried it with so far. I think this is going to get a ton of use this spring and summer as it's just the perfect throw-it-on weekend shirt when you don't feel quite like a dress, especially paired with leggings or bike shorts for me. It's also a great layering option as it doesn't have too much bulk under most dresses. Over things, it can quickly be gathered into a knot; it's harder to do the belt layering trick as there's a lot of fabric since it's a tunic, and it can be annoying to knot it as the sides have a little 1in slit at the end. However--it's still completely doable with folding, just a little trickier. What I love most for summer are the loose sleeves that won't accrue too much sweat given the distance from the armpit, despite it having sleeves. It also is large enough to completely cover a size medium Brooklyn overtop.

On fit: the tunic covers my butt just barely, but I do not mind. If you want it to cover more, would size up, and would give an even looser fit, but as is I find this fit very breathable and comfortably relaxed.

On color: the pale, yellow-toned green is beautiful although a little more muted than I expected based on website photos. I've posted a comparison pic to a charcoal grey Rowena I dyed with yellow that made a vibrant green to show the differences in tone.

I have this shirt in olive & grey. I am disappointed with the olive color, I would call it celery. It's a lighter color than I expected. I have the 1x in grey and xl in olive. The body in the 1x is nice and the fit is good but the neckline is huge & showed bra straps. I have to wear a long length high neck bra underneath or it looks terrible. The olive is slightly better in the neck but for me it is still too widely cut to cover bra straps without slipping to one side or another while using a shoulder or crossbody bag
The length is great. tunic looks good on almost all body types as tee length cuts off the body at wrong spot & looks 'blocky' imo and I like the straight hem. For reference I also have 3 Everett hoodies in 1x and the fit of xl is similar to a 1x in the hoodie. I like the light t-shirt fabric and I think it will be perfect for summer with my summit leggings with enough coverage. I would have liked slightly longer sleeve but it's OK. The color choices are good and I would like to see a navy or beige. For me this so close to a perfect tee/layering shirt even with the neck issue, I would still purchase in multiple colors because the fabric, straight hem and length are so good.
I recommend overall

Fits great! Loose and comfy without being oversized. I love the Marionberry color. It’s long enough on my 5’ body that I can wear it with leggings and feel comfortable that my butt is covered. Still waiting for Aegean Teal to be restocked in my size. I will definitely be looking at other colors too!

Love this comfy soft tunic! Great color and length.

Love the fabric, color and length.
