Packing and unpacking are probably the worst parts of a trip. I have personally learned a lot about packing in the last couple months, and I thought maybe I would share my tips with you. Packing is a delicate procedure that should not be taken lightly. I used to be chronic over packer so I know the feeling of wanting to take your whole wardrobe with you and not wanting to be under prepared. I will also tell you it sucks more to drag five suitcases through customs because you didn't pack correctly. There are two different ways to pack, summer and winter, and I'll tell you about both.
Summer is my favourite style of packing because it's light and fun. You should never leave your house stuffing your suitcase. You should not have to sit on your suitcase to close it and you certainly should not be close to the 23kg (50lb) limit. You can survive on a carry on sized suitcase but I wouldn't recommend it if you are a shopping addict or need to take along your memory foam pillow. For hot destinations, you need few things, depending on your itinerary but I'll generalise it and you can customise it.
Socks & underwear (x the amount of days you will need them / not be in your bathing suit)
Bathing suit (x2)
Shorts (x3 max, you will probably only wear one pair)
Shirts/singlets (1/3 x days away)
Jeans/dress (1 each)
Sweatshirt/Windbreaker (1 each)
Shoes (flip flops, chucks/slip ons, runners)
Your toiletries are your toiletries, take what you need and want but try not to over pack. A few things I always take are: cheap shampoo, conditioner and body wash (in case you need to ditch them for weight purposes); hair product/ straightener; tinted moisturizer (my favourite is MAC's Studio Moisture Tint); mascara, eyebrow pencil and blush, etc; Sun Bum sunscreen and Aloe; and finally, Nivea body lotion.
Winter is almost as fun but way heavier. With winter packing, you should still not be stuffing your suitcase to the max or be close to the weight limit but you have to distribute weight - a little differently. We all know that your bag doesn't pack the same way twice so it's best to leave room for expansion. For cold destinations, you must make use of both your carry on and your suitcase to get the most out of your space.
Shirts (1/3 x days away)
Socks and underwear (x days away)
Shoes (boots, runners, converse/vans)
Sweater & Flannel (x1 each)
Again, your toiletries are your toiletries, take what you need and want but try not to over pack. Cheap shampoo, conditioner and body wash (in case you need to ditch them for weight purposes); hair product/straightener; makeup; body lotion.
Gloves/ Scarf/ Beanie
Extras: Camera; book; phone charger; converter; gum; etc.
Keep your suitcase as light and empty as possible keeping in mind you will probably buy things along the way.
