Understanding how to transition your wardrobe between seasons is important for a number of reasons-for example: a splurge can be justified because you'll get more wear out of an item-and I'm excited you want to master this skill. While some trends definitely require cooler temperatures to try, there are key pieces you can wear now. First and foremost, you need some peplums in your life (yes, spring's key silhouette is still super strong for fall). A sleeveless or short-sleeve blouse with a peplum and a pretty print are lightweight enough for summer's sweltering days and will look cute under a cropped jacket later in the year. Wear your top with a leather pencil skirt or mini and you'll be hitting on another major trend: leather (it will be everywhere come autumn). Just be sure to style your skirt and peplum top with strappy sandals to keep the overall look light. For a more work-appropriate option, try a peplum top with trousers in neutral colors paired with one bright accessory like a bold belt or simple pump. You could even add a statement brooch, if you like, which also references another big trend for fall: ornate, stone-embellished, bejeweled pieces. If you're not a brooch person, you can always go for a fabulous ring instead; something bright would look lovely with a floral peplum dress. My final transitional suggestion is a simple, sleeveless peplum cocktail frock in a deep navy blue. It's more interesting than black and would look amazing with a strappy platform now and with tights, ankle boots, and an oxblood-colored jacket in a few months.
