Look to Loewe for a standout piece that will become a cornerstone for daytime edits like this dark teal-blue calf-leather Puzzle bag. The boxy panelled silhouette can be folded flat - a detail creative director J.W.Anderson lifted from the art of origami - and is suspended from a rolled top handle or alternatively the detachable shoulder strap. Carry it alongside a long dress and a classic trench coat.
