All women are being encouraged to wear head scarves tomorrow to show their support for the Muslim community.
Some are unsure whether it's culturally appropriate and what colours to wear.
Newshub spoke to Amina Patel, a Muslim businesswoman and mother.

- Scarves in Solidarity urges Kiwis to wear scarves on Friday
She wears a hijab, the term Muslims use for a scarf covering a woman's hair and neck.
"We feel quite safe wearing it. It's like if you don't put your skirt or pants on and go to work. It's part of our clothing and I must say it's everybody's personal choice."
Amina Patel says it's totally fine for non-Muslims to wear the hijab.
Morrinsville woman Nurul Shamsul last year became the first Miss Universe New Zealand contestant to wear one.
She agrees that non-Muslims wearing scarves tomorrow is a lovely symbol.
"It's not culturally inappropriate in any means, standing together in solidarity is really important and it's a meaningful way to come together as one."
The nationwide event is all about making Muslims in New Zealand feel safe.
Newshub spoke to a young woman earlier this week who is too afraid to catch public transport after being yelled and sworn at for being Muslim, while waiting for a train in Auckland.
"In normal day to day life I only see a handful of women wearing the headscarf, so to see so many people together in one area and not just Muslim women but women who choose to wear it just to support us, that's something I can't explain into words just how special it would feel."
Patel's hijab is elaborate and has a bonnet, pins and accessories, bus she says just draping a scarf over your head tomorrow is enough.
"Even the way Jacinda wore it if you just put it and wrap it around that will be fine. Covering all of your hair, some of your hair? It's your choice."
Any colour but red is fine to wear tomorrow, and if you're in Auckland and want some help putting it on, call in to the Ponsonby Mosque from 4pm and volunteers will give you a hand.
Wearing a head scarf may feel strange or uncomfortable for some, but some Muslims said that's also part of what it takes to understand what it's like to walk in their shoes.
