A woman's lipstick is something that is deeply personal and also the key to her personal style. So why is it that so many of us are willing to settle for a run-of- the-mill lipstick? Sure we may have our go-to shades, but our lipsticks are seldom emblematic of our style and personality.

Guerlain elevates the humble lipstick to a fine, almost bespoke item with its newest incarnation of the exquisite Rouge G de Guerlain. This jewel of a lipstick that was launched by the brand in 2009 already set the bar high, with its rich, highly pigmented formula, luxe double mirror and weighty, expensive packaging.

Now it takes things a step further by offering full customisation. First, pick from one of 15 lipstick cases. Whether you go for the sleek original in a silver, gold or rose gold tone, a beautiful print in a sexy dotted Swiss design, or batik, or a textured, leather finish, there's something for every taste and preference.

Says Choy Wan, "The cases are great as they're a reflection of someone's personality. You can get the pink for someone who is sweet and girly, and for me I love black leather so that's what I would choose. It's a great gift for someone who loves makeup and wants a case that matches their personality."

Once you've settled on your case of choice, pick from 30 shades. Whether you want a classic red, a rich plum or a more outré shade like blue, you won't be disappointed by the stunning variety, nourishing formula and luminous finish of this luxury lipstick. Says May Wan, "It's very easy on the lips — it's moist so it doesn't dry out. And I love the colours as they're a great blend of bright and light shades!

Finally, to add a truly personal touch, have your Rouge G de Guerlain engraved with your name, initial or a personalised note. The perfect gift for a treasured friend or the ultimate indulgence to treat yourself to, here's a lipstick case that may soon become a makeup heirloom.

Guerlain is available at the Cosmetics Department, Level 1, Takashimaya Department Store; TANGS at Tang Plaza Level 1; Metro Paragon Level 2; Sephora ION, MBS, Suntec, and Sephora.sg.
