Chanel's Coco Mademoiselle is my signature scent and have been using it for years! I always bought the 100ml bottles until I broke one while travelling (heartbroken). So I have been buying the Purse Spray since the tragic accident. Not only is it portable but I found that if I do end up dropping and breaking one (not yet so far!!) it's only 20 ml and I still have the rest of my refills in a safe place instead of losing 100 ml all in one go :(
