The sun has arrived – and if you're asking what should I wear today, here are 7 formulas worth repeating

For most of us in the UK, the sun has officially arrived, which is cause for celebration. And if you're frantically searching "what should I wear today?" we're here to help. According to the Met Office, the upcoming week is delivering highs of up to 21°C across the UK with some milder temperatures throughout the week.

Temperatures are set to be warmer than the previous week, so it is definitely time to welcome breezier staples and lightweight layers and adapt our outfits accordingly. Not only is the weather something to consider, but your everyday schedule, too and this guide factors in both the week's daily forecast and a range of daily activities, building outfits that will work hard in your spring capsule wardrobe.

From breezy cotton dresses and espadrilles for sunny spells, to a sharp blazer paired with simple t-shirts on cloudier days, here are seven outfits that will carry you through the week ahead in style and comfort too.

What should I wear today – Saturday

Tomorrow, temperatures are set to reach highs of 21°C, which means we can officially bare-leg. A slip skirt is a polished choice, yet it is comfortable enough to wear all day long.

Try out this leopard print style from British clothing brand Rixo, it's a fashion-insider favourite, and by adding this vibrant red cardigan from ME+EM, you'll feel spring-ready! You could always layer up with tights like these from M&S if you sense the chill.

What should I wear today – Sunday

Sunday remains warm with temperatures at 19°C and some cloudy spells. If you're heading out to meet friends or family this Sunday, you'll likely want to wear something elevated, and a shirt dress is the perfect choice. Most spring dresses can be dressed down with your most comfortable trainers, just ensure you choose complementary colours.

This striped shirt dress from Boden is an elevated choice and is made from a breathable linen fabric, perfect for the warmer season. It will look excellent layered up with a lightweight spring jacket for added warmth if the temperature drops.

What should I wear today – Monday

Tailoring will help you enter the week in style, and it works for when you're heading into the office or simply running errands. The best trouser suits are capable of making you feel and look your best. Pair this pinestripe blazer from Zara with the matching trousers and layer the jacket over a simple white t-shirt.

Monday's forecast predicts that it will be 21°C in London; however their will be some unexpected showers, so make sure to pack an umbrella. You can take off your blazer in the warmth, and lightweight knitted t-shirts are a spring styling hack that's perfect for milder temperatures. Mondays are usually busy, so you want a practical handbag to finish off your sharp tailoring, and Dune's Deliberate bag is the perfect find.

What should I wear today – Tuesday

Tuesday is mild with temperatures back down to 14°C, and a denim dress paired with trainers is the chicest uniform for mild spring days. A denim shirt dress can be styled for a variety of occasions and can be layered up with a blazer or jacket on cooler days.

Try pairing this denim dress with your best white trainers, a warm suede tote bag from Radley and some statement earrings. If there's an unexpected chill in the air, layer up with a light trench coat like this shower-resistant style from Next.

What should I wear today – Wednesday

This Wednesday, most of the UK is expected to be warm but cloudy with highs of 18°C. With the overcast sky predicted, we'd still reccomend wearing layers just in case the weather turns.

A lightweight shirt, straight-leg jeans like these from M&S and some open-toe shoes create the ultimate smart-casual formula. Ideal for those with busy schedules, this combination is smart and intentional yet versatile enough to transition from daytime to evening.

What should I wear today – Thursday

Jeans and a blazer are a failsafe choice on busy weekdays, especially if you have evening plans. This Thursday, we can expect warmer temperatures with highs of 17°C, but some cloud, so light layers are a must.

Pair a blazer with these bestselling straight-leg jeans from M&S. Opt for a white cotton t-shirt underneath this formula, like this one from M&S, and when the sun appears, you can take off your blazer with ease. Finish this outfit formula with smart leather loafers.

What should I wear today – Friday

This Friday, temperatures are warm with highs of 21°C; so a floaty cotton dress paired with a short spring jacket will work perfectly for this weather, and this outfit formula also works for both daytime outings and evening plans too.

Try styling your midi-dresses with espadrilles for a rustic, warm-weather finishing touch, and add some gold jewellery.

Ultimately, the trick to answering the daily question of "what should I wear today?" is to build outfit formulas that you can adapt to whatever the weather and your schedule hold. Thoughtfully chosen staples, from slip skirts to colourful knitwear pieces and comfortable footwear, can make getting dressed feel simple rather than stressful. By investing well in versatile staples that balance comfort and style, you can move through the week with more ease.
