As I explained cosplay is very broad and it is down your interpretation what it is. Some people just enjoy the occasional cosplay at events and some like to take it alot further. Over the last few years cosplay has so much evolved and expanded. It has even expanded alot more then cosplaying at a convention with cosplayers modelling in cosplay now. There was the fashion modelling then in the 1980s and 1990s alternative goth modelling became quite popular and over the last few years we now see cosplay modelling.
Like modelmayhem, folio32, liptick lenses and modelling websites where a model can showcase her/his work they are many cosplay websites where a cosplayer can showcase and show off their cosplays to a global audience. Now many of these websites are not very industry based and are hobby/amateur based but it is a start if you want to show off your work to the world and hopefully one day will get noticed.
Here are a few websites which I think are good for cosplays.
This is the main international cosplay community website. You can set up an account and upload your photos in the main gallery. Unlike many portfolio sites it is not a social networking site but the forums are quite friendly and very useful for costume construction, make up and on contact lenses. People will always help you out and offer advice.
This is basically the Japanese cosplay.com but it is getting more international. This is a social networking site and has some industry and small cosplay businesses like cosplaygen. As Cosplayer's Cure gets bigger perhaps it will have more industry links and contacts. From an amateur point of view it is an excellent website where cosplayers look stunning so if you are researching how a person looks like the character in 3D you will find excellent examples. From a modelling point of view, Cosplayer's Cure is a great site as it advertises upcoming events in Japan and they are lots of cosplay models on it. The photos are artistic and you Will find that many cosplayers think out of the box. It is also a good site for people who are just fans of cosplay and they can sign up to the non cosplay account.
What is also great about this site, people can follow your cosplays, add you to favourites, get a fan club going so when you upload a photo they will be notified. You can also add cosplayers to your favourite too.
I find this site very friendly and have made friends and contacts.
This is a UK based cosplay portfolio website. I joined this as it is local. This is a good site, as it is somewhat linked to the industry and mainly reveals upcoming cosplay events in the UK. The forum is very helpful too. It tends to be abit dead for comments but I met one or two people who are nice and they seem to be always updates on events.
This is a new social networking site set up for cosplayers internationally to meet photographers. It was set up by a well known cosplay photographer Shiroin. It is very quiet as it is only new but hopefully it will pick up.
American Cosplay Paradise
I just joined this site and it is suppose to be the best for getting links to the industry. ACP work with anime industry people and promote events at American anime conventions and do photoshoots. There are also cosplay photographers on the site too, so it is somewhat a social networking site for making friends and for getting contacts. Cosplayers on the site are really good and many of them take part in proper photoshoots so you will be able to get advice on modelling and research what makes a good photo.
That's really it for mainly cosplay portfolio sites but they are many others that you can join but they don't just specialise in cosplay they are;
DeviantArt - Fantastic for cosplay portfolio as you can join cosplay groups submit your photos, get noticed and get fans, also network with fan artists.
ModelMayhem - A great site for models very international and has many cosplayers and cosplay photographers on it. Has many industry people on it who are linked to cosplay.
Folio32 - a modelling social networking website which has alternative models on it not just fashion so cosplay would be welcomed.
Lipstick and Lenses - Another Irish modelling social networking site, seems to be not that active but it is new so hopefully it will take off.
At the moment there is no dedicated Irish cosplay website but with cosplay, anime and comics getting more popular equals more events, I am currently working on setting up an Irish social networking website named Cosplay Ireland where cosplayers can showcase their work, meet photographers, make up artists, cosplay commissions, designers, become models and will hopefully have links to the industry and events.
