Is four pair of undies for a week-long holiday enough?
According to travel bloggers Mark and Mim, it is.
After three years travelling around the world, the Melbourne couple know a thing or two about packing.
In light of airlines cracking down on carry-on luggage weight, we lured Mark and Mim into the ABC Everyday studio to share all their packing secrets.
How you pack your items is important, but what you choose to take is the key to sneaking in under the 7-kilogram allowance.
We asked Mark and Mim to pack us up for a week-long trip "somewhere sunny", but they said anything shared here can be stretched out for a longer trip.

Compartmentalise and roll
Mim and Mark's number one tip is to use multiple satchels to separate clothing, shoes and toiletries within your bag or suitcase.
They also maximise space and allow you to keep everything compartmentalised for easy access.
"On top of that, we roll all of our clothes to save some extra space in the suitcase," Mim says.
Clothing (and underwear)
"We start with the four T-shirts and we have neutral colours," Mark says.
"We have a pair of pyjamas and some workout gear if you're feeling like you might need that," Mim says.
"[Pack] a pair of bathers and some underwear as well — generally about four pairs and you can wash them as you go.
"A jumper for those chilly evenings, and we also have a dress for those just-in-case moments."
For our bottom-half, Mark and Mim recommend one pair of jeans and one pair of shorts — sticking with the neutral theme, so navy, denim and black.
If you want to pack for all weather, you'll likely want to take a jacket.
Wear that on the plane, and if you need two, "wear both of them".
"You might look a bit silly, but it saves you packing it into your luggage," Mark says.
Shoes
A pair of versatile sneakers "that look nice" and slides is generally enough to get you through a week, recommends Mark.
"If you think you want to go hiking or do something more, you can wear your hiking boots or high heels on the plane," he says.
"It saves you packing them — they generally weigh a little bit more than normal shoes."
The couple also pop their shoes in a satchel to save space and keep them separated.
"We don't want any mud coming back with us," Mim says.
Toiletries
Because toiletries and make-up can weigh so much, Mim recommends keeping them to a minimum.
"A couple of powders, one brush maybe, a small eye shadow palette and you're set," she says. "You don't need to bring your whole make-up case with you."
The couple are huge fans of soap and shampoo bars. They take up less space and are kinder to the environment as you're cutting down on plastic bottles.
"[They] really help in reducing the amount of size and weight within your bag," Mark says.
"[It] also helps with going through security as you don't need to take them out and put them through."
Liquids and documents
Make sure liquids and documents are within easy reach inside your carry-on.
"We've got a foundation and lip balm [for example] … these go in the front so that as you're going through security, you can just pull them out," Mim says.
Important documents go inside the front zip so they are "nice and safe but still easily accessible".
