one fits, other too big
Size: X-Large, Color: Navy/Sage Green
The good: made with a nice fabric, a good weight and soft. Color for both shirts is what I expected. I wish I could keep just one shirt. The navy blue tank top fit perfect and was comfortable. Green, same size as the blue one, was uncomfortably big. Arm holes 2 whole inches larger than the blue top. This type of inconsistent sizing is frustrating.

Good quality, not sure on fit
Size: X-Large, Color: Black/Mariner Stripe
I looked at the general comment on this top and it stated frequently returned due to loose fit. My measurements are close to size xl so I figured if they run large/loose then they would fit me fine. My bust is 46 1/2" and I probably should have gone xxl. The tops are snug across my breast and I will have to be adjusting so it does not pull a gap at the side of the arm pit area. However the top is not too snug, also not loose throughout the rest of the body so don't know how I would feel about a size larger. The quality is nice, medium weight cotton. No see through and no falling in creases. I hope washing these in cold and line drying will keep them from shrinking. I will keep these because I do like the quality and length but have not decided if I will order more or not.

Weirdest armhole proportions I've seen
Size: X-Large, Color: Navy/Sage Green, Size: X-Large, Color: Navy/Sage Green
There are a few nice things about these tanks -- I like the colors, there's a little extra length in the back, and the fabric is a thick quality fabric. I appreciate the fact they're 100% cotton and was looking forward to wearing these.
Overall, the tanks fit as I would expect for the size. But what in the world is up with the dimensions for the arm holes? There is a significant amount of extra fabric that bunches up and looks awful (see photos) I've never had this happen on a tank top before, even one that's a size up. It's really strange and I'm disappointed that I can't keep these because of it.

Comfortable Sleep Tanks, Weird Fit for Daytime
Size: Small, Color: Hot Pink/Oatmeal Heather
These 100% cotton tanks are perfect tops to wear at home: soft, breathable, and great for sleeping or lounging. The pink is extremely bright (borderline highlighter), while the beige is a much more wearable, calm color. The fit is a little odd on me—something about the cut just doesn’t sit right—so I wouldn’t wear them out of the house, but as a comfy bedtime set of two, they do the job.

Very reasonable price for the quality
Size: Small, Color: Navy/Sage Green
The tank tops are well-made with quality fabric. I like the subdued colors, too. Unfortunately the tank tops don't fit me well.
