Many people suggest smelling coffee beans in-between fragrances to 'reset' your nose (and avoid anosmia or nose fatigue) so you can tell the difference between scents. But... you're really just smelling another strong scent.

"The best trick to combat anosmia is to take a piece of fabric (shirt sleeve or a scarf) smell it and then start the process of 'sniffing' all over again," suggests Phillips. "Or sniff your elbow, where the skin is usually unscented, and then start evaluating the fragrances again. You will be amazed at how quickly you will be able to identify the fragrances. It's clearing the palate."

Phillips says it's important to let the perfume sit for a few moments after spritzing (without rubbing it into your skin) so that you get the actual smell of the fragrance after the alcohol dissipates.

Well, it depends on how long you want your fragrance to last as they all have different concentrations. "The strongest most concentrated form of fragrance is perfume or parfum," says Phillips. "It has the highest percentage of essential oils, mixed with alcohol and distilled water. The more you dilute it the less concentrated it becomes. So after perfume, is eau de parfum, then eau de toilette, and the lightest form is eau de cologne. The higher the concentrations, the longer the fragrance lasts," she says. Just a few important distinctions when it comes to making your scent selections.

It's all up to you, says Phillips: "It's a question of preference. If you find a fragrance you love, you can wear it all year round. It then becomes your 'signature' and it is wonderful when you love a perfume and it really reflects your personality and individuality."

She also says that personalization of a scent is very popular now, so you could also consider having a scent made specifically for you and then have it customized for different seasons.

Also, there's nothing wrong with sticking to one signature scent or having a casual fragrance for daytime and a more sophisticated one for night time or special occasions.

When you were younger you might have preferred sweeter, fruitier fragrances and as you grow older you might like something more woody or spicy.

"Just the way one's preference for food changes over the years, the same might be true for perfumes. As we age, the number of cells that detect aroma in our nose start to diminish, the nose lining begins to thin, and hormonal fluctuations influence our scent preferences. This decrease in smell capability limits our ability to taste as well as changes the aromas we prefer," she says.

In other words? Be prepared to redefine your signature scent over the years!
