Packing a suitcase is not an easy task for a lot of people.
You don't want things to look messy inside, you don't want creases or stains on your freshly washed and ready for a meeting clothes. Besides, suitcase should be light and easy to carry. Ideally, you would have clothes for several meetings, night out, gym outfit and maybe a comfy weekend things. But how to pack all that and not carry half of your wardrobe just for a one-week trip?
There is a simple rule: 4 tops + 3 bottoms + 2 jackets + 1 dress
+ pumps + flats + handbag + clutch
Simplicity is the by-product of a good idea and modest expectations.
