Clothing can dramatically affect our moods. Consider how that favorite red blouse offers an immediate confidence boost, or how that sunny yellow cashmere sweater is the perfect antidote to a rainy Saturday.

Emily Spivack, founder and executive director of Shop Well with You, wants to help women with cancer empower and nurture themselves through dress. "Our goal is to get people to wear what they feel most comfortable in," says Spivack. "If you're in the midst of treatment and feeling down, putting on a lively color can make you feel energized."

Fabrics and styles can make a difference too. When revamping your wardrobe, remember: "There are absolutely no rules," says Spivack. "Do what makes you feel most comfortable and confident about your body ‑- and what helps you move past cancer diagnosis." Her top pointers:

Consider the color. Warm hues (like red, cranberry, rose and pink) can be easier to wear if your complexion is sallow or washed out from the chemo, says Spivack. However, if green puts an extra skip in your step, by all means wear green. Spivack notes that everyone is different ‑- and everyone has a different skin tone ‑- so there is no one-size-fits-all approach.

Reach for feel-good fabrics. "Women should be in tune with what feels good on their skin," Spivack says. Natural, breathable fabrics like cotton, linen, silk and cashmere are soft and nurturing. (A good first layer: an ultrasoft cotton or cashmere tank top.) Abrasive fabrics can rough up skin that is already facing radiation's sunburnlike effects. By all means, opt for low-maintenance fabrics that can be easily laundered.
