Good enough. If you roll your clothes rather than folding them "stacks", there can be a lot more of them. And I speak from solid experience.
Roll up your clothes when packing
You can kindly pack for a week in a carry-on suitcase; it's just a matter of being able to roll it. And, of course, about the following items on my packing list.
Sort your hand luggage carefully
Once you've packed what you consider vital, you can start sorting. You are guaranteed that you won't need it all - I almost dare you to promise that.
So always take some out of your suitcase again. You don't know if there are sales where you are going, do you?
Travel Goods
First, think about how essential it is to you to include conditioner and shampoo in your packing list.
You could utilize something if you're lodging in a hotel. A tiny bucket won't hold enough if you have to go for a long time, in which case it will be simpler and less expensive to make a purchase when you get there.
Your best pals in this situation are travel-sized and miniature versions of your best-loved items. Little jars, buckets, and bottles that hold face cream, scrub, and shaving foam to catch it all are your second best buddies.
