The rest of the women's range reads like a paint chart, and I mean that as praise. Each bottle has its own color and its own mood, so you can shop by the tone you want to walk around in.

Yellow Diamond Eau de Toilette is the sunny one by name and, to my nose, by mood, a light scent that suits a day outside. Dylan Turquoise Pour Femme Eau de Toilette is the lighter of the Dylan line, a good pick for a hot commute. Dylan Blush Pink Eau de Parfum with Floral Gourmands is the sweet one, where soft flowers meet something edible, and Dylan Purple Eau de Parfum is the deeper, more grown-up cousin in the same line.

Then there are the two Crystal Noir bottles. Crystal Noir Eau de Toilette and Crystal Noir Parfum Spray carry the Crystal name into a darker, after-hours mood, the ones I associate with evenings and long dinners. The parfum is the fuller of the pair, and I would keep it for cold weather.

A useful habit with a colorful family like this is to buy by the situation. Turquoise for the gym bag, Blush Pink for weekends, Crystal Noir for nights out. That way each bottle gets used, and you do not end up with a shelf of scents you only wear on birthdays. It also makes gifting easier: if you know your friend loves the cold, clean Turquoise feeling, you already know which neighbor on the shelf she would enjoy.

If Bright Crystal is your idea of a good scent, you will probably like the fruity florals from other houses. They share the same shape: a juicy top, a flower in the middle, and a soft musk underneath.

Yves Saint Laurent's Libre Berry Crush with Raspberry is the tart, bright one, with a raspberry sparkle right at the front. Viktor&Rolf's Flowerbomb Pretty Peony with Peony and Strawberry is the sweeter, fluffier option and the closest to the peony in Bright Crystal. Armani Beauty's Power of You with Passion Fruit is tropical and cheerful. Miu Miu's Fleur de Lait with Coconut Milk is creamy, more like a soft cardigan than a spray of juice.

Jo Malone London's Peony and Blush Suede Cologne with Jasmine is the lightest of the group, a proper cologne that fades in a few hours and suits someone who dislikes strong scents. LoveShackFancy's Sweetheart with Raspberry and Peach is the most playful, a sugary, pastel scent for spring picnics.

What I would skip: buying a full bottle after smelling only the opening. Fruit notes come first and leave first, and the peony or musk you live with all day shows up later. I would also skip a rushed test in the middle of a crowded shop, where every other perfume in the air muddies your nose. Smell coffee beans or your own sleeve between tries, and stop at three. I would also skip spraying two different fruity perfumes on the same wrist, since raspberry, peach and passion fruit can turn to fruit salad.

The only way to know a bright floral is to wear it through a full day. Spray one wrist in the morning, keep the other bare for comparison, and check at the two, four and six hour marks.

Notice whether it gets soapy, whether the fruit fades and whether the flowers still feel warm. Store the bottle in a drawer, away from a bright window, because citrus and fruit notes are the first to turn. Take a note of how many times you catch yourself smelling your own wrist, because that number is more honest than any first impression. Then ask a friend to hug you and tell you what she smells. And if you find a scent you keep going back to, it deserves a spot on the shelf, wherever it came from. If you want to keep browsing, I also put together Gucci Perfume, Starting From a Scarf Made for Grace Kelly and Versace Eau Fraiche.
