While this summer saw the heyday of gladiator sandals and wayfarer sunglasses, the fall is sure to usher in an entirely different set of staple pieces. The colder months mean bundling up in layers of clothing, in which accessories become even more essential to accent an ensemble. So whether it's conversation piece jewelry or functional handbags, who better to know the new Fall must-haves than the industry insiders themselves?

With Fashion Week coming to a close, and the temperature swiftly lowering, psychoPEDIA took to the streets to find out what New York's trendsetters can't live without this season:

Lara
Jewelry Designer for Kelacalaq

My essentials for this fall are jewelry pieces with brass (Subversive Brass Cuff, $1105) . Also, different things that are purple—from gloves to fringy bags (Chloe Purple Slouch Bag) and ponchos. I also love this purple Smashbox Photo Finish Lipstick (Enchanting, $22) I got in a gift bag at the Ports 1961 fashion show.


Maxime
Russian PR Manager for Carolina Hererra, Nina Ricci, and Prada

My favorites would be Calvin Klein rings, and Ray Ban glassses, for the moment. For watches, it depends on your budget, but Charmex (Milano Gent) makes great ones for men.


Ariela
Editor at InStyle

I think this fall, the most popular accessories will be a statement necklace or big earrings, like the ones Subversive makes (Cluster Bracelet, $1800). And for a fragrance, Anouk Eau de Toilette ($74) perfume is great for the cooler season.


Elissey
Fashion Director of Citizen K Magazine

During the summer, carrying smaller lighter bags is great. But in the fall and winter, larger bags are more convenient– I love ones from Lanvin. As for shoes, I like Pierre Cardin and Yohji Yamamoto. More generally, fall essentials would be spacious clothing, to feel more comfortable. I’m also really liking futuristic accessories like bags made of plastic or fake leather and transparent sunglasses, like ones from Balenciaga.

Owner of online retail store, Buy Definition

For shoes, lace-up and rugged boots will be great this fall. I really like the “Crushed” style by Devotte. I also think tie-dyed and hand-dyed scarves will be a big look this fall–- Sunshine & Shadow makes one. And for necklaces, Fenton/Fallon makes great larger, chunky necklaces.

Rochelle
Jewelry Designer for Ralph & Duchess

This fall will be all about outrageous statement jewelry and metal and feather headpieces-– things that aren’t normal for jewelry to be made of. Catherine Holstein’s show had really cute hats, and I also love the Kate Spade mock crocodile gloves. I’m also planning to be wearing my Rick Owens leather jacket.
