Kosovorotka shirt, use this model but color it like on other pictures
Decorative belt
Please, don't draw her in modern clothes!
And now about clothing. It is not 100% autenthic. She is a girl, but wearing boy's clothing. Like typical Russia "kosovorotka" shirt and pants, that are more from vikings :D Her shirt has model like on picture, but is green with yellow flowers and red ornaments (like on other pictures). She tie her shirt with decorative belt. And wear bast shoes like all poor people in slavic middle age. Even she is not poor at all, because she is "magical creature" (better naming will be "small god")
