August and September are awkward months to dress for in the UK. Late summer to autumn outfits are the smartest way to dress for the UK’s unpredictable August and September weather. Mornings can feel cool, afternoons can still be warm, and rain can appear without warning. The best transitional outfits are built from light layers rather than heavy autumn clothing.
Quick answer: Keep a summer base – tank, tee, dress or light shirt – and add one removable layer such as a cardigan, blazer, suede jacket or lightweight trench. Jeans, loafers, ballet flats and trainers make the late summer to autumn outfits switch easy.
