Plus sized carriers

Ok so I know I have seen a post about this and I can't find it. I have a carrier that was given to me that fits my husband just fine, but for me it's not gonna work. I am wanting a carrier that can grow with my baby. I have seen the Moby, but has someone used another one that might be helpful? I like the back pack style carriers over the material... Any help? I am a size 24 prepregnancy.
