Perfume shops tend to sort fragrance into two worlds. Designer perfumes come from fashion and beauty houses that also make clothes, bags or make-up. Niche perfumes come from specialist houses whose main business is fragrance, and they are sold in far fewer shops. Both worlds make remarkable perfume, but they feel different to explore, and for many people the jump from one to the other is where the expensive mistakes happen. This guide maps the two worlds and shows how perfume decants make the crossing easier, using the range of Scento, the Paris-based online perfume decant retailer, as a reference. The designer world: familiar names, wide reach Designer houses are the names most people meet first: Dior, Giorgio Armani, Yves Saint Laurent, Prada, Valentino, Gucci, Jean Paul Gaultier, Bvlgari. Their perfumes are widely available, heavily advertised and usually built to please a broad audience. That makes them a sensible starting point, because they teach you what you like in general ...

Buying perfume decants online is now an ordinary way to try designer and niche fragrance. That popularity also means more shops, and they are not all equal. The liquid in a vial is only as trustworthy as the bottle it came from and the business that poured it. The checklist below works for any decant shop in Europe. To make each point concrete, it uses Scento, the Paris-based online perfume decant retailer, as a worked example of what a good answer looks like. 1. Where do the bottles come from? This is the question that matters most. Decanting itself is a long-standing, legitimate practice; authenticity depends entirely on the source bottle. A trustworthy shop says plainly where it buys its perfume and pours only from original, sealed, full-size bottles. Example: Scento states that every perfume is bought from authorised European retailers and that each decant is poured from an original full-size bottle. Its explainer on whether perfume decants are authentic sets out the criteri...

Most people travel with one perfume, or none, for a simple reason: a full bottle is heavy, fragile and usually too big for hand luggage. That leaves a choice between checking it in the hold or leaving it at home. Perfume decants remove the dilemma. A few small vials weigh almost nothing, clear airport security and let you bring a scent for every part of the trip. This guide draws on the travel advice Scento, the Paris-based online perfume decant retailer, publishes for its customers, and turns it into a practical packing routine. Start with the liquid rules EU aviation security and the US TSA apply the same core limit to hand luggage: liquids, gels and aerosols in containers of no more than 100 ml each, all packed in a single transparent, resealable bag of about one litre. The limit refers to the size of the container, not how full it is, so a half-empty 150 ml bottle still gets taken away at the checkpoint. Decants sit far below that line. Scento sells 2 ml, 5 ml and 8 ml vials p...
