"They're like a throwback to the original Birkenstocks with the double thick strap," Avidan-Cohn said. "There are a zillion copycats now, but the actual original Birkenstock in a solid black or white, or even a black patent, is trendy again."
Good for all ages, and for all-day walking or a day at the beach, this slide worn with a lightweight white cotton shirtdress, for example, is displacing delicate strappy sandals of seasons past, she said.
A lot of the styles are adjustable. Black is a popular color that Avidan-Cohn likes with a white pedicure.
Wide, cropped pants
This spring look is floating into summer, hitting at the midcalf.
"A lot of women say, 'Oh I have short legs. I can't wear cropped pants.' But it's just a matter of hemming the pant to your midleg," Avidan-Cohn said.
And by wide, she means culottes wide.
"They require a more substantial shoe, a chunky shoe whether it's flat or with a heel," she said. "I like to see the waist on these pants, so I like a shirt that hits where your natural waist is at the top of the pant, not showing any skin."
In shorts, the high-waisted style paired with cropped tops that also aren't belly-baring — hitting just below the waistband — is holding for summer.
Bucket styles, cross-body bags instead of clutches and a fresh crop of bright, flower-soft backpacks are high on Blumenthal's list for summer.
She sees versatile, lightweight and hands-free schlepping in backpacks at a variety of retailers, both high-end and more affordable.
