Can typically be identified thanks to the attire's characteristics: a red dress with white fur trim, a red fur trim cape, a yellow and green sash attached to a white bag containing gifts, and red boots with Star-shaped buckles.

Note that it's possible (especially for older artwork), to depict Cecilia in a winter outfit without it being the one described above, in which case this tag should not be used.
