I LOVE Flickr. I think it’s the best service available for organizing photos. It has sets, tags, groups, editing tools, a great upload interface, mobile functionality, and pretty much anything else you could want from a photo sharing website.
There are a lot of fetishists on Flickr who you will have to wade through. That may be something to consider if you think it would make you uncomfortable to be added to the favorites page of someone with, say, a stockings fetish, or occasionally receive leery comments. I usually block that sort of person and it doesn’t bother me anymore, but your comfort level might be different.
If you do join, make sure you add your photos to the wardrobe_remix group because it gets a lot of traffic. Just make sure your photos follow the w_r rules if you submit there (it has to be an outfit you actually wore in everyday life, it has to be a full-body photo, it can’t be a mosaic/composite photo, and there has to be a description of what you’re wearing).
Feel free to have a look at my Flickr if you haven’t already!
