The Diptyque Perfume Brooch (£84) is literally the most wearable fragrance yet, as you simply pin it on your clothes. And with no contact to the skin, you needn't worry about your skin reacting to it. Each pin houses a tiny scented disc — available in Eau Rose, Do Son, and Fleur de Peau — that you can pop in and out as you please. The scent stays strong all day, and if you pop the disk back in its pouch after, we've found that it will easily last a month. Plus how cute is the gold-plated bird?
