The between-season weeks are when most women feel they have nothing to wear despite having a full wardrobe. It's too warm for the coat, too cold for the summer dress, and the wool jumper feels wrong but the linen shirt is inadequate. This is a real problem and it has real solutions, none of which involve buying entirely new clothes for each transitional period.
Transitional dressing is not a special category. It's a different way of using what you already own, with a few specific pieces that function as bridges between seasons. Get those pieces right and the awkward weeks become opportunities to wear the most interesting combinations in your wardrobe rather than the most annoying dressing challenge of the year.
The pieces that bridge every season
A lightweight turtleneck in a neutral color is one of the most useful transitional pieces in existence. In late summer to autumn, it goes under dresses that were purely summer before, instantly making them autumn-appropriate. In winter to spring, it layers under a blazer when a heavy jumper is too much. In a merino or cotton-modal blend, it regulates temperature well enough to work in mild conditions without overheating.

The blazer is the other essential transitional piece, specifically a relaxed-fit tailored blazer in a medium-weight fabric. Too heavy and it's suffocating in mild weather. Too light and it's useless against cold. A mid-weight Italian wool or ponte blazer sits in the temperature range that covers most transitional days. Worn over a t-shirt with jeans, it handles early October and late March equally. Over a blouse with trousers, it can replace a coat on mild winter days.
Layering without looking bundled
The reason transitional layering looks wrong on most people is volume. They add a layer over something that already has volume and the result is shapeless. The solution is to keep the base slim. A fitted top or slim-fit knit under a blazer or structured shirt reads as intentional. The same blazer over a chunky oversized knit reads as accidentally wearing all your clothes at once.
The length relationship between layers matters too. An outer layer that's longer than everything underneath (a blazer longer than your top, a shirt longer than a vest) gives a deliberate, considered silhouette. Layers at the same length compete with each other. This is why the tuck works so well in transitional dressing: tucking an inner layer into a bottom removes that length competition entirely.
Late summer to autumn: the specific challenge
This is the transition people find hardest because the impulse is to abandon summer clothes entirely before the weather has actually turned. A linen dress with a fitted long-sleeve underneath and a leather boot is not a confused outfit. It's September dressing done correctly. Similarly, a summer midi skirt paired with a fine-knit crewneck and ankle boots looks intentional and feels comfortable in the 14 to 18 degree temperature range that defines early autumn in most of Europe.
A trench coat (opens in new tab) is the outer layer that makes transitional dressing make sense. It works over summer dresses and winter sweaters alike. It looks deliberate in September and still functions in November. If you own one good trench and one lightweight blazer, you have the outerwear solved for every transitional period.
The winter to spring shift is easier because the direction of travel is more forgiving. You're removing layers rather than adding them. A winter outfit without the heavy coat is already most of the way to a spring outfit. The only additions needed are lighter footwear and a willingness to swap the wool jumper for something in cotton or linen before it fully feels warm enough. Dress for what the weather is becoming, not what it has been.
