That's it. No fine print. No time pressure. Just shop with confidence. 🤍
That world ended in the 90s.
Today's fashion industry is run by business people. Not fashion people.
Stanley Marcus, heir to Neiman Marcus, wrote it plainly in Quest for the Best: "When you talk with an independent fine-quality maker, he speaks with pride about his product; when you talk with the chairman of a large corporation, he refers with pride to its net profit and balance sheet."
Hubert de Givenchy put it more bluntly: "There is no more fashion."
In an industry where the designer has been reduced to a commodity, Alessa is something rare.
Family-owned. Independent. Designer-led.
Alessa is the impossible dream of two girls in love with fashion. We built her without outside financing, without shareholders, without anyone to tell us that fashion should come second.
Let us show you what's possible - design, quality, price, magic - when the power belongs to a designer-founder, not a profit-hungry financier.
2. 30 Years of Luxury Craftsmanship
A team with three decades in luxury fashion - including a pattern-maker who has crafted pieces for Balmain and Givenchy.
Our ateliers also produce for some of the most prestigious fashion houses in the world. The same hands. The same standards. A fraction of the price.
3. Exclusively online
No store markups. No wholesale layers. No unnecessary costs. That’s how a €200 piece can compete with one priced at €800.
4. Up to 70% Italian Fabrics
Including premium Italian and deadstock fabrics often used by renowned Italian and French houses.
5. Limited Quantities
Fast fashion produces in the hundreds of thousands. We produce in limited runs - often with unique fabrics that can't be repeated. Many styles sell out for good. Don't wait too long.
Comfortable
Very good quality and craftsmanship
There are no more comfortable pants!
Incredibly comfortable, met my expectations. Thank you for the amazing design.
I\'ll happily shop from your site again.
The quality is on point!
Gorgeous design, fabric, and everything. I recommend them 😍
True to size and shapes the body!
The pants are amazing. I have the beige ones too, both in size M. The fabric of the black ones I'd say has slightly less stretch. I'm 163 cm, 54 kg.
Fully true to size. Shapes the body and looks elegant and beautiful.
The fabric is amazing. It hugs the body snugly, the feeling is wonderful.
The pants are amazing
Exceptional pants! The quality is perfect — you can tell from the first touch of the fabric. Light, soft, and very pleasant to the touch, elegant and comfortable at the same time. The biggest plus for me is that the length is ideal — they don't end above the ankle like I usually get, but fall beautifully along the leg. The size fully matches the size charts, fits wonderfully, and highlights the figure.
Unique and one-of-a-kind in their style
Unique product, I wholeheartedly recommend
.
Cut, fabric — unique as always. ❤️
Fits my look perfectly
Thank you
It's unique!
Perfect cut and amazing fabric!
They're amazing, comfortable and stylish! Thank you!
Style and class! The design and fabric are unique. True to size, elongates the silhouette. I'm sorry I didn't order it sooner. Highly recommend!
Perfect! Looks incredible! The fabric feels great to the touch!
The pants are amazing in terms of cut and fabric, and they shape the body perfectly. Incredibly comfortable and stylish.
Exceptionally beautiful pants! The cut, fabric, belt — once again I'm impressed! On top of that, you're very smart — you know how to make your customers feel special! 🥰
Exceeded my expectations — it's like they were tailored just for me. Amazing fabric, feels like a second skin ♥️♥️♥️
Girlsss, the pants are wonderful!!! The most beautiful piece in my wardrobe!!! Thank you for the personal note too!!! You're amazing!!!
Gorgeous cut and fabric. It hugs and shapes the body. I was very skeptical but this is a gem that goes with everything
Incredibly comfortable and stylish! Favorite style. I also have the lighter color. I'm charmed. Highly recommend.
Unique
Top quality!
Even better in person!
🥰
The pants are very nice, unfortunately the L size doesn\'t match!
Sorry it didn\'t fit — the waist feels more like an S.
Unique, to put it mildly — amazing!
The fabric and quality are top-notch!
It wasn't my size!
Like every product of yours, once again I'm absolutely thrilled with what I received — the quality and the way it fits. All I can do is thank you again, stay healthy and blessed, you're simply THE BEST
Brilliant execution! The most beautiful pants combining style, class, and comfort. They highlight the figure while being so soft to the touch and comfortable.
Incredibly soft and pleasant fabric to the touch. Amazing pants. You're wonderful ❤️
:)
Exchanging for a different size
Amazing find!
It's great.
I rarely write comments about clothing and generally don't leave reviews for anything. But this time it's different! In short, the pants are amazing, they fully met my expectations (I actually had doubts whether they'd fit). I think the best criteria I could share that would be useful for future customers is the sizing... I'm 67 kg and 1.60 cm tall. I'm curvier, and despite that the L size fit me perfectly. They're comfortable, no bunching, no tightness in the hips and thighs... in a word, this is a real find. Don't hesitate if you're looking for comfort and style in one. The size is spot on!
Gorgeous, stylish, elegant
The fabric and the style are amazing :)
Perfect, ordering another one.
🖤
Amazing cut, nice fabric, the built-in belt makes the pants even more beautiful. Perfect for both the office and everyday wear.
Amazing fabric, cut, and design. Bravo! I'm satisfied! 💝💝💝💝
The pants are very stretchy and look wonderful.
Incredibly precise cut and stitching! Amazing quality! I'm very happy because even after one wash it looks like it was molded to me.
The pants are amazing
You lived up to my expectations
😘😘😘
Very elegant style! Fits the waist perfectly and highlights the curves in a bold and sexy way. The fabric is fine and pleasant to the touch. An excellent pick for the spring season.
The trousers are unique. They beautifully shape the body and are incredibly easy to style.
Very nice, stretchy, high-waisted, true to size🖤
❤️❤️❤️
Fits perfectly on the legs. Number 1
I can't say too much about these trousers yet, but one thing's for sure: when I want trousers I can put on without needing a tailor's alterations, I order from Alessa.
Gorgeous trousers, they sculpt the figure. Dense and firm fabric.
Really nice fabric... Ideal for everyday wear...🙃😊😍
The trousers are unique.
Unique! Amazing design and fabric. It's as if it was custom-made for me — fits both in size and length. Can't wait for the rest of my order. You're incredible, lovely girls.
Unique! Amazing design and fabric. It's as if it was custom-made for me — fits both in size and length. Can't wait for the rest of my order. You're incredible, keep it up!
Wonderful trousers, stretchy, look amazing
I had zero hesitation about keeping or returning them — they exceeded all my expectations. Quality, beautiful and practical.
Amazing style! I love everything about it, but what I'm happiest about is the length. For me this is the perfect length and I'd love for all trousers to come in this length so I don't have to get them shortened. Can't wait for the rest of my items from the new collection! ❤️
Very pleasant and stretchy fabric. Comfortable and versatile — great for both a casual look and a dressed-up one with heels. True to size.
The cut is wonderful and looks great. Unfortunately the fabric is quite low quality — in less than a month of wear, on the right side, those fuzzy little pills already appeared and ruined the whole look of the pants. The care instructions you recommend didn't help — they're not the same pants anymore.
Fits the body amazingly, but unfortunately the fabric is terrible — after the first wash it pilled and threads are sticking out.
I hope you'll re-release the product with better fabric. Until now I've never had this issue with the fabric of my other trousers from you.
I like the trousers, but the fabric started pilling on the very first wear. That disappointed me.
The trousers are great — the cut, the execution — but the fabric pills after the very first wear. I removed the pilling with a fabric shaver, but it keeps appearing in other areas where there's friction.
The trousers are amazing and look incredible, but there's one remark that unfortunately I noticed only after washing. The left leg has a twist, which in my opinion (I used to work as a pattern cutter) is caused by cutting off-grain. It's visible both when hanging and when worn, but during the initial fitting I only paid attention to how they sat at the waist.
