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.

The pants are great and comfortable
The jeans are great, for me they are a bit tight only at the waist.
The jeans look stunning. They smooth out everything and definitely boost your confidence. I'll be wearing them with pleasure.
The jeans are amazing. Ordering from Alessa for the second time and I'm fully satisfied with the quality!
Soft temptation ❤️
Soft and comfortable! They sculpt the body!
The jeans look stunning! They're stretchy and hug the body. The waist is exactly what I imagined. They go with everything!
True to size and perfect for many different combinations.
The jeans are amazing! Highly recommend ❣️
They're gorgeous in person! They shape the figure and fit great. The photo doesn't show clearly that they have seam details. In my opinion the sizing runs small, but they're wonderful.
10 out of 10
Amazing fabric and super comfortable!
The jeans are incredible! 😍 Very comfortable, practical and sexy!!! 👌
True to size! They look gorgeous on me!
Good cut and fabric. Runs quite small — at least one size. But they're a wonderful choice for any season.
Gorgeous cut and very soft, pleasant denim. I wear them with pleasure!
The jeans are perfect. They hug and highlight every curve. Comfortable and beautiful.
My favorite jeans ❤️
They became my favorites from the first wear! Comfortable and incredibly cozy, they sit beautifully on the body and shape in all the right places!
They fit perfectly and the length is ideal
The jeans are very comfortable, soft and look amazing. I rarely like jeans on myself, but these became my favorites!
I like them and wear them with pleasure! Thank you! :) You're wonderful!
The most gorgeous and comfortable jeans.
The jeans are amazing, the fabric is dense and they sit really well. Probably some of the few jeans where I can say they genuinely shape the body beautifully. I love that they truly have a high waist and give overall form! After two wears they loosened up a bit, which is normal for jeans, but if someone like me is torn between two sizes, you might want to order the smaller one.
The jeans are true to size and stretchy. They highlight the body beautifully — these are my first Alessa jeans but they definitely won't be the last. I feel class and style every time I'm wearing Alessa 💖
Great
Whatever I say won't be enough. I have absolutely zero complaints — everything about these jeans is 11/10, the embroidery is unique!
10/10
I have no words to describe how blown away I was when I saw them in person! The fabric is incredibly comfortable and soft, and the cut is amazing — they fit my body as if they were custom-made for me. They elongate the figure, shape the bum, hips and waist so well that they even smooth out the tummy. They're simply incredible... I can't stop wearing them! Thank you, Alessa team!
The jeans are amazing, exactly what I wanted. A must-have in every woman's wardrobe. They shape the body beautifully!
They're gorgeous! Incredibly feminine, comfortable and stylish. True to size, in my opinion.
Gorgeous jeans. The new logo is fantastic.
Comfortable, great for everyday and the office. Can be dressed up for more formal occasions too. Thank you!
The jeans are very soft and comfortable ❤️
Comfortable, great for everyday and the office. The cut is excellent, adds elegance. Can be dressed up for more formal occasions too. Thank you 💜
Comfortable, trendy, favorite trousers. With tall boots they look perfect.
The perfect jeans! They became my favorite the moment I put them on — every centimeter fits me like a glove, as if they were made for me! They're unique ❤️ Highly recommend!
They're amazing, fit perfectly.
Beautiful, stylish and comfortable!
The jeans look amazing, they sculpt and shape the body.
The jeans are unique! If you only knew how long I'd been waiting for exactly this style in a rich black color! Perfectly true to size, not too long, and they look amazing while slimming the figure. I'm very happy!
The jeans are amazing! Incredibly detailed craftsmanship, they shape the body beautifully and I'd even say they elongate the figure. I would have liked the black to be a touch more saturated, but I'll still be wearing them with pleasure! Perfectly true to size.
A bit loose on me, maybe XS would have been better, but overall I'm not disappointed
The jeans are amazing and remarkable — they're worth every penny!
All your styles fit me perfectly! True to size, perfectly shapes and highlights the body, the length is great too and the denim is quality! Thank you!
The jeans are simply unique, a true jewel! Very soft and comfortable. Yet another incredible product from you! I'm thrilled and will be wearing them with pleasure! Thank you Alessa! 🥰
Amazing jeans. They have stretch and don't squeeze. Perfect for boots or dress shoes. ❤️🤌🏼
All your jeans work like magic creating incredible shapes 😇😉 The size is perfect. Comfortable, yet they hold in the tummy and sculpt the bum.
The jeans are very nice!
The jeans are gorgeous! Perfectly true to size :) Very beautiful and comfortable! And the new logo is simply unique! 💗💗💗
The most unique jeans I've ever bought! ❤️
The best and most comfortable jeans I've ever had, true to size, highly recommend. Thank you 🩷🌷
For the first time I won't need to shorten an Alessa pair of jeans! Everything is unique — fabric, cut, stitching, world-class quality! But once you shorten them (as I always had to)... the style falls apart... and that always held me back
The jeans are wonderful, but for size M they're way too tight — they fit like an S.
The jeans are stylish, soft and comfortable — exactly what I wanted to have. They don't match the XS sizing — I had to get them taken in and they're still too loose and baggy on me!
The photos don't show the bottom part of the jeans.
Runs slightly small!
