An outfit for Barbie.
This outfit includes a sweater, pants/trousers, leg warmers and headband.

Sweater is worked in one piece.
Pants are worked one leg at a time, then legs are joined and knitted together to waist.

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, except for Italian version that comes in a .pdf file.

No specific yarn or gauge is given in the pattern.
Usually Sticka till Barbie patterns call for 4 ply mercerized cotton yarn or other fingering yarn, and gauge for stockinette stitch is given in the yarn page of the site.

Notes about translation:

English version: what is called “pattern rib (k1, p1)” is actually fisherman’s rib. The pattern given in other languages is “knit the knits in the stitch below” (and purl the purls, I suppose).

Version française: il y a une erreur de traduction. Le point employé pour le pullover est similaire à les côtes perlées, mais il y a seulement à répéter le deuxième rang. C’est-à-dire tricoter à l’envers les mailles à l’envers, tricoter double à l’endroit les mailles à l’endroit, et ça pout tous les rangs.

Versione italiana: Il maglione è diverso dal modello originale. La misura dei ferri, il numero di maglie da avviare o lasciare in sospeso, la costruzione stessa del capo. Inoltre il punto scelto non è a coste semplici: non ho trovato il corrispettivo nome italiano, ma le istruzioni dicono di lavorare i diritti doppi, cioè nella maglia sottostante la maglia sul ferro (e i rovesci normalmente a rovescio, suppongo). Il bordo in fondo va lavorato per 3 ferri a coste semplici con i ferri più sottili, il collo per 1 cm a coste operate e per 3 cm a coste semplici.
