Off niche items

For now, we are quite content with the categories for buying and selling that CosComme host on the platform and will work to develop these niches in order to reach their fullest potential.

Cosplay, costumes, community and everything else in between. We are the marketplace of choice for pre-loved costumes, from the straightforward all the way to the showstopper. At CosComme, we believe cosplay is not just anime. It is that, and so much more. A cosplayer’s choice is limited only by one’s imagination. We respect the creativity, talent, and skill of every cosplayer, from the choice of clothing material, prop, headgear, up to being the character one chooses to be when the right time comes. We believe that cosplay can be part of everyday life. A renaissance headband here, a superhero mug during coffee breaks there, a manga-inspired wig to go along with your work outfit, scarves, caps, neckties and many more. The possibilities are endless. One can come home and admire anime-influenced artwork on the walls as part of home décor. Anyone can cosplay.
