I personally have a fashion blog on blogger, it's: http://ryannsrunway.blogspot.com I like blogger because it's easy to use, customizable, and it's completely free. I really love it a lot! Oh, and I know you can forward your own domain on blogger(idk if you can on the other ones, I'm guessing probably on wordpress, but probably not on tumblr).
Now, although I've never used wordpress myself, people who use it say it's really good, but I'm pretty sure some of the features on wordpress cost money(I think just the more advanced features, that aren't necessarily needed). And, I would suggest NOT using tumblr, I just feel like the blogs on there aren't real blogs(just my opinion--I don't feel like they're blogy enough lol), they feel more like an upgraded version of twitter or something, to me. So it's almost like a lite or diet version of a regular blog lol.
Matter of fact, ive noticed that a lot of people who have blogs(on blogger, wordpress, etc.), will have another little mini blog on tumblr, where they just post a few pictures, and share a few separate things that might be off topic to their regular blog. With saying all that, I'm actually not completely against tumblr or anything, I'm just not sure if it's the best place to start a fashion blog on. Hope this all helps you make the right choice!
If you still cant decide you could always test them out for a few days, to see how each of them work, with out actually publishing or posting anything, and then you could delete the other two once you decide.
Wordpress is best, I prefer it over the rest as far as blogging about stuff consistently. Random blogging I use tumblr.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
