I ordered "Favorite Red" in a small (which they have as a 4-6). The product came via standard shipping, so it took about a week to arrive. The shirt was nicely folded and had tissue wrapped around it, which was nice because my shirt was very crisp and clean looking!
I was a little worried at first, because I am quite petite (but have a bigger chest) so I wasn't quite sure if it would fit (I usually wear size 2), but my mom is a 4-6, so I figured I could give it to her if it was too big. I tried it on first and was surprised that it fit me very well...even the length (usually shirts are very long on me). I held it up to my mom and we both realized it would be too small for her. I think the sizing is what you would expect from a typical small, medium, or large, so I would focus on that rather than the sizes they put beside it (because I think it is close but not 100% accurate...).
So what about the shirt itself? Well, I loved the color! It was very vivid and rich-looking in color. The shirt is made out of cotton, so it was very comfortable. I like the length of the sleeve as well. If you are petite, I would definitely recommend this product. Even if you aren't...it is still a good shirt, but those of us who are petite know that it is incredibly difficult to find a t-shirt that doesn't look like it's engulfing us. I also was pleased that my bust was not pulling in the shirt, which often happens. The shirt looks really great and feels really nice too! This is going to be a staple in my wardrobe now...especially because it actually fits my body (WOOHOO!!!).
