Although Leavanny-made clothing is rarely preferred for everyday use, these pokemon have developed immense popularity among cosplayers. Industrial, mass-produced sewing is more than capable of supplying wardrobes which do not particularly stand out, and drove Leavanny from their historical role of sewing textiles through economies of scale, but the flashy, iconic outfits worn by most fictional characters require far greater craftsmanship to create, and many who wish to wear them find their efforts time-consuming and insufficient.
It is with good reason that the Leavanny are called a cosplayer's best friend, for even a sewing machine can not compare to these pokemon in speed. Leavanny are not particularly well-versed in the stories which inspire cosplayers, for their insect eyes do not allow them to be taken in by the illusions on which television relies, and their leafy hands which sew so well can not turn pages. For this reason, they require a great deal of assistance both in patterns and materials from the cosplayer, but given proper instructions these pokemon can put even elite cosplayers working on their own to shame. Then again, few such cosplayers exist; the highest ranks of cosplay contests are typically filled by Leavanny trainers who learn extensively from their pokemon, even if they raise this pokemon for display instead of battle.
Increasingly, the remarkable craftsmanship of the Leavanny has been recognized outside the walls of convention centers. Pokemon contests have always contained a significant display element, and the skills which make costumes of anime characters are just as valuable for making original outfits to be worn by human and pokemon alike. To be sure, they are not worn to emulate the outfits of favorite characters, but those characters wear costumes for the same reason that coordinators do; to look as impressive as possible.
