Here are just a few :)
25FLONDON is a relatively new blog, but you wouldn't know it without looking at her blog archive. Her blog is amazing. Gorgeous photos, interesting blog ideas, and beautifully written posts. You know when you find a blog and you almost feel angry that you didn't find it sooner? That's 25FLONDON for me. You'd be doing yourself a disservice not to click on that link ;)
Formerly Best of Beaute, A Vain Woman has a clean and crisp layout with again, amazingly clear photos and swatches. Cecilia's blog posts are always well-written, informative, and interesting.
I love Penelope's blog because not only is she beautiful, but when writing a review, she always includes product photos, clear swatches, and photos of the product in action (actually used on the lips or eyes, etc.). Admit it: We all love seeing those photos because we know how useful they are, and yet so many of us are guilty of not including them in our review posts. (For me, it's usually due to laziness. Just being honest.)
This last blog isn't beauty related, but it's more of a life blog. Naomi is adorable, her husband is adorable, her English bulldog is adorable, her baby is adorable, and together, they make a super adorable little family. It's not a fashion blog per se, but both Naomi and her hubby have amazing fashion sense and the blog, as a whole, is really inspiring and fun to read.
So, there you go! Four fantastic links that are just begging to be clicked on ;)
