Sandals - Sturdy, comfy walking shoes are essential for navigating the cobblestone streets of Europe. Avoid pancake-flat ones or thongs and go for breathable leather sandals with cushioning.
Sunscreen with UVA and UVB protection - Buy your sunscreen before you fly as it may be more expensive in Europe. Look for SPF50+, broad-spectrum and water-resistant ones.
Rain poncho - While you’ll no doubt experience cloudless skies on your trip, a European summer can be unpredictable (especially if you’re in the UK). Pack a poncho that you can easily whip out on walking tours in case it starts to drizzle.
Layers - Layering will be your best friend in a European winter. Go for a merinowool thermal base layer (it retains heat well); a mid-layer such as a button-up shirt or light sweater; an insulating layer, such as a polar fleece; and an outer/shell layer to protect you against the elements – a good-quality, breathable jacket should do the trick.
Waterproof shoes - Boots may be bulky, but they are your best friend for the city streets and wet ground. Throw in some waterproof hiker-style shoes too if you can find room in your case.
Gloves - To prevent your fingers going numb, opt for cashmere-lined, leather gloves. If you’re keen to take photos on your phone, go for a touchscreen pair – that way, you won’t have to take them off when you’re snapping.
Lip balm - While it’s great travelling in autumn and winter, you can experience everything from winds to sunshine. Keep lips soft and smooth with a protective, organic lip balm that doesn’t contain petrolatum.
Cardigans and light jumpers - They’re the perfect partners for trans-seasonal dressing, and they won’t take up much room in your case.
Leather ballet flats and loafers - A European style staple, they’ll take you from museum to Merlot with ease. For men, a pair of loafers will do the job.
