Save packing space — and prevent wrinkling worries! — by laying trousers or jeans, unfolded, so one half lays inside the suitcase and the other half hangs over the outside. Repeat around all edges (skirts, blazers and dresses are also ideal).
Once you’ve surrounded the bag with these “overhanging” items, fill the inside of the suitcase with your tops and toiletries. When finished, fold over the hanging parts of the garments and neatly over the contents.
Keeping skirts and trousers UNfolded keeps them UNwrinkled, too.
