- Finally, a trouser that's made to flatter a round tummy.
- The fit is incredibly comfortable, just the right amount of stretch.
- The comfiest pair of trousers I've ever owned.
I recently purchased the Amalfi MELYRFLEX Wide Leg Stretch Trouser in Black, and I couldn't be happier with them.
As someone who values both comfort and style, these trousers exceeded my expectations.
The fit is incredibly comfortable, just the right amount of stretch. They don't dig in at all, which made them perfect for a night out that included drinks and a three-course meal. I felt comfortable from start to finish, while still looking smart and stylish.
I also love supporting Melyr as a slow fashion brand. Knowing that it's run by a dedicated husband-and-wife team makes the purchase feel even more special. The quality, comfort, and thoughtful design really shine through.
If you're looking for trousers that combine elegance, comfort, and ethical fashion values, I would highly recommend these.

Lurrrrrrrrve these trousers. Im a size 16 , bottom heavy. Hate my chubby legs and I have a small waist. Today I wore my Melyr trousers. The first time I wore trousers in years... (mostly because they never fit properly and are uncomfortable) well there's a new breed of trouser in the house and now I need more. Love love love xxxx
Lovely trousers just a shame don’t have bigger sizes
The first thing I did when I received these trousers this morning was to try them on. Not just any old try on....
I tried all the moves I need to do, working in a school..... crouching down next to a desk looking at a pupil's work, moving quickly to break up a tense moment between pupils, walking very fast down a corridor to locate a pupil. And then being able to enter a classroom still looking professional, not readjusting my clothing every 30 seconds.
I can confirm that top marks were given to the trousers. No gaps between top and bottom half, no-chafe from walking quickly and plenty of stretch for crouching. Thanks Melyr ❤️
Trousers arrived promptly, nice material but sadly, much too short so have had to return.
Fitted well. Very promptly delivered
Love these trousers, so comfortable. More colours please.
Beautiful trousers, great fit, however the Sienna cut is not for me. I prefer the Amalfi cut which I re-ordered and tried again, it’s fabulous.
Fabulous trouser. Finally, a trouser that’s made to flatter a round tummy. These trousers are just incredible, they allow you to wear clothes that flatter your shape and don’t add inches. Premium fabric and cut. Highly recommend. My only regret, not thinking of the design idea myself!
Exceptionally comfortable, go with everything trousers. Quality fabric that does not need to be ironed. And great customer service from Melyr.
These are fabulous, well.made trousers which smooth out the midsection lumps and bumps.
Wash very well too. True to size.
Lovely comfy ponte type trousers with the added benefit of the waist support which I like very much.
Hi Alison,

Great fit and just the right length for me. I am going to have the pockets sewn up as they stick out but other than that fit is good
Hi Dawn, thanks for your feedback! We're glad the fit suits you. Sewing up the pockets sounds like a great idea for a smoother look. Let us know if you need anything else!
So good a trouser that I have multiple pairs which I can just pull out of the closet without having to think what goes with what.

After reading all the reviews and measuring myself carefully, I decided to order — my first trouser purchase in a decade! My waist pointed to a size 16, but my hips measured closer to a 22, so I went for an 18. I was anxious, but I needn't have been. They fit beautifully and are oh so comfortable. I'm absolutely delighted, and catching them on sale made it even better!

Why MelyrFlex
Designed for changing bodies
i.
A waistband you forget
MelyrFlex sits inside the waistband and holds without digging. It moves when you sit and recovers when you stand. Nothing to fasten, nothing to adjust.
ii.
Four-way stretch
Lightweight fabric that moves with you and resists creases. It goes in the machine at 30°C and comes out of a suitcase ready to wear.
iii.
Seen on real women
Every pair is photographed on real women, so you can see how they fall before you choose.
