A tube dress for Barbie with turtleneck/polo neck and very short sleeves.

Look for pattern by number at http://www.stickatillbarbie.se.
The website is in English & Swedish, but patterns are available in several languages.

On the website you’ll find the patterns listed on the left, by number, grouped on pages.
Accessories like hats, scarves or bags are listed in the accessory section, below in the left column.
Click on numbers to open a page, look for the numbered image, then for the link to the desired language below it (clicking on the image will only enlarge it).

This pattern comes in a .doc file.

Pattern calls for specific yarn only in some languages, this information is missing in others.
Gauge is not given in the pattern but you can find it in the yarn section of the site.
