Does the slim fit run small?

It is cut close through the chest and waist, so it fits trimmer than a regular tee. If you are between sizes or want a looser drape, take the larger size.

It is cotton, described as soft. The listing does not state the fabric weight, so expect a standard mid-weight jersey rather than a heavy or sheer tee.

How should I wash it?

It is machine washable; follow the care instructions supplied with the shirt. Wash cold and tumble low to limit shrinkage and color fade.

Can I wear it under a jacket or shirt?

Yes. The slim cut and crew neck layer cleanly under an overshirt, knitwear or a casual jacket, and the turquoise adds color at the neckline.

Is this a good everyday t-shirt?

It works as a casual basic with a strong color. It is not a heavyweight or athletic tee, so it suits light everyday wear and layering more than hard use.
