There's no denying it - trouser suits are trending right now. If you're contemplating buying a new summer suit for the invite you have in your diary, you've come to the right place. I've been scouring the internet for the most stylish suits around - and I should know because I'm obsessed about them - but more on that later! 

Trouser suits work for everything; the office, a wedding, a christening, a nice meal and even a hen party weekend. I declare that we're officially in 'stylish trouser suit season'. When the weather is playing up like it is for us right now (one minute it's sunny and then next it's raining), you can always count on a trouser suit to make sure you feel comfortable for a special occasion.

I'm going to confess something - I'm addicted to two-piece trouser suits. Honestly, it's bordering on ridiculous. I've loved trouser suits for years, and wear one for nearly every important social occasion in my calendar. I'm even wearing one in my HELLO! profile picture. I don't know what it is, but when I wear a suit I just feel like I have my life together. I feel like a confident girl boss. I feel like I can do anything. I also love that I don't have to think too much about an outfit as a whole, and you can mix and match the separates.

As wedding guest season approaches, now's the time to start thinking about the special events you have in your diary for 2024. Trust me - a suit will work for everything. Whether you're after a white suit or a rhinestone suit, floral or a timeless tuxedo suit, check out the list below. And we're loving all the three-piece suits that are everywhere right now, so we've included links to the matching waistcoats as well, just in case you want to go full on with the look.

How I chose the best trouser suits 

  • Popular brands: I shop at all of the brands within this list, if I'm choosing my favourite suits it's best that I pick brands I shop and love.
  • Inclusive sizing: Where possible, the suits in this list are for all shapes and sizes.
  • Versatility: The best thing about a suit? The way you can wear the jacket and trousers separately and you've got more looks for the price of one.

It's not just me who loves a power suit. Celebrities and influencers, and royals love to dress in a two-piece. Whether it's Joey King wearing a green Bella Freud suit, or supermodel Naomi Campbell in fuschia pink, Katie Holmes in white with a colour pop shoe, or Duchess Kate in purple - a smart trouser suit makes for a great outfit choice.

How to style a trouser suit

You have three ways you can wear a suit. Casual for daytime (see Hailey Bieber for inspiration - or look to Trinny Woodall on Instagram), smart and elegant like Victoria Beckham, or as evening formalwear à la Margot Robbie. As a side note: My obsession with suits wouldn't be a thing if I had to wear them for work - I can totally understand if you want to opt out of this trend because you feel like it's 'boring workwear'. However, you could try a more relaxed approach to a trouser suit, or choose a colour you wouldn't dare wear in the boardroom. 

I personally think trouser suits look great with T-shirts and white fashion trainers, I also love them glammed up with sexy stilettos and a chic clutch bag. I would steer clear of cross-body bags, as the chain or strap across the body might ruin the shape of the jacket. Jewellery-wise, it's totally up to you. I love a pair of statement earrings with mine if I'm wearing for an evening, but if it's daytime, I usually stick to gold chunky hoop earrings.

Can you wear a trouser suit to a wedding?

Definitely. If you're wearing a trouser suit to a wedding, obviously don't opt for white (unless you're the bride!) and go for bright or jewel-toned colours instead. Or even a printed suit for extra impact.

How to dress down a trouser suit for daytime

If you want to dress down a trouser suit, it's easy! Team with a a pair of white fashion trainers or a pair of strappy sandals for a formal event. Trinny Woodall is the queen of power dressing in sneaks.

What shoes to wear with a trouser suit? 

For a special occasion, I like teaming a trouser suit with a sexy stiletto or a strappy sandal or a mid-heel sandal (comfort is key!). A seamstress once told me that if you're wearing wide-leg trousers, the hem should fall halfway down the heel. Also, don't underestimate the fashion trainer - I love wearing my suits in the day or out to dinner with a pair of Veja trainers and a simple white tee. Flat shoes can be tricky, but ideally you would see some skin - you don't want to look like the trousers are wearing you.
