The best Reformation dresses...
We’ve been consulting our data (because numbers don’t lie people) to see exactly which styles you, the Cosmo readers, are adding to your basket.
From dreamy silk dresses perfect for date nights, to the best maxi dress picks for weddings, graduations and birthdays, these are the silhouettes you keep coming back for. Over the past year, the top five Reformation dresses our readers have shopped and loved are (drumroll, please):
Best Reformation wedding dresses
If you’re the blushing bride-to-be, a browse of Reformation’s wedding dress selection never goes amiss. Treating us to an edit of luxurious silk maxi dresses, playful minis, and floral beauties, there’s a smattering of stunning new styles to suit every bridal occasion – think your hen party, reception, rehearsal dinner and the all-important honeymoon.
If you weren’t already swooning, get this: Ref has a gorgeous range of short wedding dresses for those who want something a little different (or just want to show off some leg). From A-line numbers and to slinky, Bardot minis, to love-sleeve designs for the winter bride, these frocks aren’t the usual high street wedding dress culprits — they’re crafted from luxe silk fabrics with custom embroidery and exquisite tailoring.
Ideal for anyone having a civil ceremony, as this occasion is less so about the ballgown and more about expressing your personal style – so a timeless, practical shorter silhouette is always a good idea. Beautiful as they are, they’re also super-affordable, with all of our shortie picks coming in at under £500.
Best Reformation bridesmaid dresses
Okay, so your best friend has asked you to be a bridesmaid – yay! But now comes the slightly daunting task of finding your own dress. If you’ve been given full creative freedom to choose a style, fret not: Ref has a gorgeous selection of dresses in an inclusive range of silhouettes and sizes. So finding the perfect dress can feel personal, while still fitting in with the wedding aesthetic.
A few things to consider: do you want a style that cinches in your waist, or something with flow and movement? Are you drawn to a strapless neckline to highlight your décolletage, or a halter to accentuate your shoulders? Do you feel most confident in a structured A-line dress, or would a sheath silhouette suit your shape better?
You’ll also be pleased to know that Reformation often offers the same style in a beautiful array of shades. So if you’ve been asked to stick to a particular colour palette, rest assured – Ref has you covered.
Best Reformation wedding guest dresses
Sure, planning that big day is stressful, but figuring out what to wear to a wedding as a guest is a task in and of itself. Luckily, Ref has a stunning range of pretty midis and sweeping maxis that work for all occasions. If you’re flying off to a destination wedding, think romantic florals and breathable, floaty fabrics. A countryside venue dress code strikes the balance between polished and effortless, while a traditional church service is the perfect excuse to opt for something elegant and timeless.
Slip into one of these beauties – the Jillian Silk Dress is a personal favourite of our Shopping Writer – and your only concern will be making sure you don’t accidentally upstage the bridal party.
