Beach Bum

I’ve been a Matthew Williamson fan for as long as I’ve had pocket money to buy Vogue.

I remember pouring over his shows and photos of Sienna Miller wafting around red carpets in his chiffon creations.

His designs the embodiment of feminism, bohemian glamour and who I wanted to be.

One of British fashion’s true greats.

So naturally I couldn’t possibly be more excited to be the one to introduce you to his newest collection! A collaboration with The Outnet and the reason I popped over to Mykonos to put the pieces through their paces.

Matthew Williamson X The Outnet -1

Hey, it’s a tough job but someone’s got to do it!

The collection ranges from slinky little bikinis to billowing gowns.

All you need to take you from pool to party, and everything in between.

Purple bikini // Straw hat

Matthew Williamson X The Outnet -5

I fell particularly hard for this silky little number

Matthew Williamson dress-1

made for those Greek blues.

Matthew Williamson X The Outnet -7

Matthew Williamson X The Outnet -8

The lightest blue and white silk, pulled in at the waist and tied neatly at the collar.

Pair with heels and a clutch for dinner, or slip on sandals and a basket for an afternoon of exploring.

Just the thing for drinks at one of Matthew’s favourite spots, a bar on Little Venice.

You can’t miss it, just look for the best view!

Though if you’re feeling adventurous, you might want something more substantial.

A classic one-piece in timeless blue and white, perhaps.

Matthew Williamson X The Outnet -17

A low back, spaghetti straps, cinched in at the waist with a plunging neckline.

Matthew adores women and this shines through in his work.

Swimsuits just don’t get any more flattering than this.

Do Not Disturb Hat

It’s so exciting to be working with Matthew & The Outnet on this new launch.

Shop the collection here, but if you want to grab a piece or two for the summer, be quick.

The Outnet discounts mean that collaborations sell out in the blink of an eye.

Now you sea them, soon you won’t!

    Rosie, thanks for introducing us to these beautiful swimsuits! Can you provide any advice on the sizing- e.g. is a size 10 a small? There’s no guidance on the website.

    So beautiful! This really makes me longing even more for Greece.
    About something else – I saw a glimpse from your home at Snapchat when you showed the cool top you were wearing the other evening. I’m so curious about your interior at home! It looks so pretty and I really like the blue and white pottery/porcelain and lamp! So if you feel inspired at home some day, you would inspire all of us even more with a blogpost from your home! ๐Ÿ™‚ Hope you are well! xx

    Rosie, love your blog! But am not receiving any posts past “beach bum”. I’m from the USA if that matters to help fix the problem. I’ve seen a few comments on Instagram mentioning this issue. I can’t wait to read your updated posts as I really enjoy your writing!

  • That blue dress looks absolutely wonderful! <3

  • Lorraine

    Love the book you were reading! Actually read it when I was living in London last year for my studies, found it a bit difficult to get into at first but loved it at the end! What did you think about it?
    Lovely pictures as always, by the way.

  • Beautiful, beautiful post! You were recommended to me recently and it’s obvious why! ๐Ÿ™‚ x
