I have a love/hate relationship with fashionista: sometimes the content is really half assed. fashionologie.com can have occasionally have information that no one else has. And jezebel.com has a regular feature called rag trade, but that site is particularly liberal and feminist so it will not suit all. The New York Times has a blog named the Moment which is hit or miss, and style.com has a similar blog which can be kind of insider-ish. The Cut is the best that I know of, and I check it obsessively. I also love the personal blog of aspiring model Lauren Stovel at itslasfactory.com. Poor thing is stuck in Nevada and dreams of the catwalks!
