What Made the Cut
Starting from Top Left:

Revlon Colorstay 16-Hour Eyeshadow Quad in Seductive, $7.50, drugstores.
When Trish surveyed her shadows, the only brights she had touched were purples. So: She'll pare down to this quartet.

Sephora Collection Outrageous Volume Mascara, $15,
Volumizing mascaras add both length and fullness.

Rimmel London Natural Bronzer in Sun Glow $6, drugstores.
Trish loves bronzer. But a single powder formula, two shades deeper than her complexion, is the only one she—or any woman—needs.

Shu Uemura Eyelash Curler, $19,
One lash curler (repeat: one) is a must in every makeup collection. It makes lashes look longer, eyes more open.

Mary Kay Lip Liner in Soft Blush, $12,
A pencil that's close to the color of your lips is the only lip liner you need.

Lancôme Le Crayon Khôl in Black Ebony, $25,
This is the black eye pencil Trish grabs most often ("It's easy to apply and doesn't smudge"). She can toss her other 32.

Shiseido Luminizing Satin Eye Color Trio in BR 307, $33,
Most days Trish uses beige and brown shadows to define her eyes. This palette gives her three beautiful shades.

Laura Mercier Tinted Moisturizer SPF 20, $42,
Trish always returns to this formula—and no wonder: It leaves her complexion luminous.

L'Oréal Paris Colour Riche le Gloss in Nude Illusion, $8, drugstores.
Trish's lip products can be narrowed down to three: this sheer gloss and an everyday tawny shade and a festive red.

Bobbi Brown Blush in Nude Pink, $24,
With a rosy tint on her cheeks, Trish looks more bright-eyed. A medium pink powder with the slightest shimmer is particularly flattering.

YSL Touche Éclat, $40,
Trish owns three of these highlighting pens (unbeknownst to her). She doesn't have significant dark circles, so she can pitch her pots and sticks of concealer—this light formula is enough to brighten her undereye area.

Clinique Chubby Stick in Whole Lotta Honey, $16,

Chanel Rouge Allure in Excessive, $33,

Bobbi Brown Eye Shadow Brush, Blush Brush, Powder Brush, and Angle Eye Shadow Brush $28, $50, $60, $28,
Every time Trish visited a makeup counter, she bought another (pricey) brush. But with just these four, she's covered.
