The Trend: Matte Fuchsia Lips
Seen at: Giles, Dries Van Noten, Rue Du Mail

The usual soft, girl-next-door pink gloss was upstaged this season by a brighter, high-wattage version of the hue. At Giles, makeup artist Lucia Pieroni prepped lips with foundation to erase natural color, then dabbed on hot pink lipstick and patted it down with translucent powder for a matte finish.

To keep the look fresh, go for minimal makeup on the rest of the face.

The Trend: Opaque White Nails
Seen at: Rag & Bone, Moschino, Honor 

Graphic, modern and universally flattering—it's no surprise designers fell in love with this neutral hue.

Our product pick: Tom Ford nail lacquer in Vapor, $30; nordstrom.com.

To get nail pro Jin Soon's clean take on the trend at Rag & Bone, stick with a shorter, slightly rounded shape. Buff nails to prevent bumps from showing. Since the opaque shade tends to dry matte, finish with a shiny topcoat.

The Trend: Sleek Hair Knots
Seen at: Ralph Lauren, Michael Kors, Gucci, Chanel, Prada, Naeem Khan

Move over, messy buns. The prettiest example of summer's refined look: intricate chignons and elegant woven knots. At Ralph Lauren, hairstylist Guido Palau shellacked hair back with blow-dry lotion, wrapped it into a knot, and secured with pins.

The Trend: Blue Lids
Seen at: Altuzarra, Just Cavalli, Michael Kors, Monique Lhuillier

Blue eye makeup was as ubiquitous as black and white and ruffles on the runways this season. In heaviest rotation were shades of aqua, cobalt and turquoise, but makeup artist Tom Pecheux demonstrated the most wearable version with a simple trace of navy eyeliner at Altuzarra.

Our product pick: MAC Technakohl Liner in Auto-de-blue, $16; maccosmetics.com.

For an even sweep, use a freshly sharpened pencil and thinly sketch the line along upper rims. Use a pointed Q-tip to clean up any imperfections.

The Trend: Head Scarves
Seen at: Dolce & Gabbana, Marc by Marc Jacobs, Max Mara

Once a '60s staple, the head scarf resurrected as the standout hair accessory. To create the boho-chic look, backstage pro Guido Palau decorated decidedly messy updos with silk scarves at Dolce & Gabbana and cotton, graphic-printed turbans at Marc by Marc Jacobs.

Our product pick: Redken Satinwear 02 Prepping Blow-dry Lotion, $18; redken.com for salons.

Prep strands with a styling lotion before blow-drying hair smooth and pinning it up. Tie the fabric tightly against the head, making sure the hairline is visible.
