A more notable trend of late - an upgrade from the recent revival of the 90's tattoo choker but a heck of a lot cooler...
1. The simple leather neck tie..
...wear it loose
or wear it tight.
Double wrap it..
2. The bandana (to be worn round the neck)
Casual, a la Bella Hadid in this super cool shoot.
With delicate necklace layering...
again with perfectly layered jewellery...
3. Other (scarves, ribbon etc)...
I figured you may already have a stray bandana lying around your bedroom from that one time you dressed as a pirate for Hallowe'en but in case you want to go more upmarket, here's one by Saint Laurent (a mere £85... £90 if you include net-a-porter's £5 shipping charge) or just find one on ASOS..
Saint Laurent printed cotton scarf (£85) on net-a-porter.com
Jacquie Aiche for For Love and Lemons bolo tie choker ($1250.. yes, that's $1250.00)
ASOS long skinny scarf (£8)
