New favorite brand!

Recently discovered this lovely brand COSSAC. The fabrics and fittings are beautiful and comfortable. Great quality and unique, timeless designs. Love that it's all European made, with GOTS-certified factories in Portugal. Make the clothes feel even better when wearing.

Gorgeous !

Perfect - great fit and great fabric!

Lena
Very cosy and perfect fit

Super cozy and beautiful sweater!
I bought size M (162 cm tall, usually buy S-M in sweaters, like boxy cropped fits, or a little oversized) and it's perfect. The arms are very long as you can see in the pictures. I wear them folded over for practical reasons, still looks very good. I really like the texture, colour and as usual the quality feels great. This is my second cossac sweater and I think I found a favourite brand.

Stunning flowy piece

Super happy with this dress. The fabric is soft light and flowy. Easy to dress up or down. I already had the jumpsuit in this colour and thrilled to have this addition to my wardrobe.

Gabrielle
Lovely top

Lovely top, and nice material, agreeable to wear.

Claire
Lovely light piece

Love the flowiness of the fabric. And have paired it with some thermals to be able to wear it in the winter. Can't wait for it to be warm to wear it in it's full glory!

Gabrielle

I was looking for a slightly thicker dress for a winter wedding and this was a perfect catch.

Krisztina
Amazing Fit - love my new jumpsuit!

Very good fit, nice material, comfortable, can be combined as sporty or for a night out - I am very happy with this choice

Julia
Nice fit

Soft fabric,thick enough and therefore not seethrough. I am inbetween sizes and was worried about the fit. I sized up as advised and the fit is perfect

Özlem Dankers-Tapirdamaz

Absolutely gorgeous dress - the blue color is amazing, and the material is honestly out of this world, so soft and fits perfectly! This is my second COSSAC dress and I'll keep coming back for more. :)
