Karen Millen Premium Viscose Linen Woven Shirt Dress With Gold Buckle Belt
Let’s take notes from Princess Kate and her iconic Me+Em pink shirt dress that she wore back in 2023.
The style is one of those classic designs which doesn’t only automatically have a smart edge with its collar and cuff details, but it’s one you can rewear season after season and it will never go out of fashion.
This Karen Millen alternative is brilliant with it’s bright pink shade and a high waist belt that can cinch you in and show off your natural curves.
ASOS DESIGN Relaxed Blazer in Cream
If you’ve already got your outfit sorted but are worried about being caught out by the unpredictable British weather then a blazer should be your go-to.
It will add a tailored finish in any outfit you pair it with, whilst providing a more expensive price tag to the ensemble.
Roll up the sleeves for a more daytime, relaxed vibe, or simply drape over your shoulders for an off-duty, fashion-forward look.
River Island Yellow Short Sleeve Asymmetric Drape Jumpsuit
A jumpsuit is always a fool-proof outfit idea when attending events such as the RHS Chelsea Flower Show as you can have control over how formal or casual you want to go.
Pair with trainers and a denim jacket for a more daytime edge, or opt for wedges and a blazer to amp up the style points.
The butter yellow colourway of this River Island option is a perfect nod to the season, whilst being too loud.
M&S Jacquard Midaxi Waisted Dress
We’re believers in dressing up and feeling your confident self at all times, and this M&S dress will give you that boost.
From the decorative jacquard fabric that gives the design subtle floral motifs throughout, the flattering peplum waistline that creates a more slender silhouette, to the punchy red hue, this is an all around winner that can be worn with sandals, heels, wedges or trainers.
Rewear to garden parties, wedding guest-dressing, or other formal occasions in your calendar.
Stradivarius Lace-up Jute Platform Wedges
You can never go wrong with a pair of wedges during the Spring Summer months.
They’re a wardrobe staple and a classic piece of footwear that are truly versatile, dressing up any outfit that you pair them with.
The neutral tone of Stradivarius’ platform wedges mean they can go with muted tones or bold brights and still look classy.
The lace-up fastening adds a more delicate feel to them.
Lipsy Yellow Floral Print Long Sleeve Grandad Blouse
There’s absolutely nothing wrong with wearing jeans to the RHS Chelsea Flower Show, especially when you style it with a nice shirt.
But why not swap a crisp white option for one that gives a nod to the event itself?
This soft pastel top comes in a more relaxed silhouette with a grandad-style collar, and bubble-sleeve hems to add more of a romantic aesthetic.
Nobody’s Child Blue Longline Crew Neck Waistcoat
Tailoring is a big trend for Spring, and when combined with seasonal shades such as this soft blue it’s a winning combination.
Take your ensemble up another level by choosing a coordinating two-piece with matching trousers for an extra £71.20 to give it that cohesive energy that will have everyone asking you where your outfit is from.
Pair it with sandals or trainers to keep it more daytime.
New Look Stone Woven Floral Corsage Top Handle Bag
Nod to the theme of the event even with your accessories with this raffia, woven style from New Look.
Its natural texture and colour means it packs versatility and can be worn with anything you choose to wear, whilst giving a classy finishing touch.
Club L London Louise Sunflower Print Wide-Leg Trousers
If you want to make a subtle wardrobe statement, and in 2026, we think we all should from time to time then these wide-leg trousers are the one.
Made from premium stretch satin, the playful sunflower print embodies the event but without overdoing it or seeming garish.
They are brilliant to dress up, or down, from day-to-night, so whatever else you might have coming up in your calendar, these will be a great go-to.
The high-waisted style will also create the illusion of longer-looking legs, and that’s never a bad thing.
Style with a plain white tee or white shirt depending on how fancy you’re feeling.
