Emily Mariko's Must-Have Products, From Diptyque to Linen Sheets

Mariko loves the comforting and soft feel of her Serena & Lily Positano Linen Sheet Set ($298, originally $398). "I really love the texture of linen. Sometimes, linen can be a little crunchy, but these sheets I found get softer and softer with every wash," she says.

These durable linen sheets are made from flax, and they're also thermoregulating. She points out that linen sheets can be a hit or a miss but notes that the ones from Serena & Lily do not shed and get better over time. The sheets come in two colors, white and sky blue, in sizes ranging from twin to California king.

Pro Tip: It's best to machine wash these sheets in a cold, gentle cycle and tumble dry on low.
