Runs true to size and well made!
Color: Black, Size: Medium
I am very pleased with the size and cut of this top. I hesitated on sizing (at 5'1" and 105 lb) because I like a looser fit and am sometimes given different size recommendations. Many times the tops are too large and must be altered or simply passed on to thrift stores. This shirt in a medium is perfect in its fit, flows nicely. The neckline is not too low, but more like a shirt with a couple of top buttons unbuttoned- no gap. The sleeve length is good for me as my shoulders are a bit narrow. (I checked and no way to remove the stitches that hold the sleeve into a cuff. They are deeply embedded into this soft opaque fabric that has some stretch. (Even with the best of seam rippers and sharp eyesight!)I think the rolled cuff is cute! Top drapes well and is a great length for jeans or shorts- dressy casual wear, with its perfect fabric thickness. I really like the black color. I would not wear it with leggings because of the length, but jeggings are great with it. The little contrasting buttons are a nice touch. Great value buy.

Super comfy and pretty
Color: Black, Size: X-Large
Fit is nice and comfortable!!! Soft in the inside as well! It’s not huge but also doesn’t stick to me. You can literally wear it down (casual with jeans or shorts) or dress up (like I did for Mother’s Day with a nice skirt and jacket) Seems breathable enough for our California heat
