Materials and care
W She is Sunday we believe that clothes should give you not only a great look but also complete peace of mind. That’s why our journey with each project begins with choosing materials that are safe for you and your skin.
Below you will find a list of materials that have captured our hearts, along with some tips on how to care for them so they stay with you for years.
-
Cotton
HOW TO CARECotton is the heart of our collections – it is soft, allows the skin to breathe, and gives that unique feeling of freedom we seek on every day off. We choose only high-quality fibers certified by OEKO-TEX®, so you can be sure that your clothing is safe and skin-friendly.
-
Organic Cotton
HOW TO CAREChoosing organic cotton is a gesture of love – both for your skin and for the environment. Grown without the use of pesticides and chemical fertilizers, it is incredibly soft, hypoallergenic, and fully biodegradable, making it the safest choice even for the most sensitive skin.
-
Viscose
HOW TO CAREViscose is a fabric that will steal your heart with its delicacy. It is breathable, cool to the touch, and drapes wonderfully on the figure. Although it comes from natural cellulose fibers, it requires very gentle care to maintain its noble shine and shape.
-
Wool
HOW TO CAREWool is an extraordinary material: it breathes, keeps you warm, and has natural self-cleaning properties. However, it does not like sudden temperature changes or intense rubbing. Treat your wool sweaters and accessories gently, and they will retain their shape and fluffiness.
-
Denim
HOW TO CAREJeans made exclusively from natural cotton fibers are a "lifetime" material. They contain no synthetic additives, so they do not permanently stretch – after each wash, they return to their original shape. Treat them with care, and they will look better year after year.
-
Lyocell
HOW TO CARELyocell is a material of the future – extremely eco-friendly, breathable, and as soft as silk. It is made from wood cellulose in a closed process, making it one of the most environmentally friendly fibers. It loves water but cannot tolerate heat, so it should be treated with a bit of care.
-
Corduroy
HOW TO CARECorduroy is our favorite for cooler days. It is durable and incredibly stylish, but its fluffy ribs do not like heavy pressure or high temperatures. Take care of it gently, and it will reward you with deep color and impeccable shape.
-
Muslin
HOW TO CARECotton muslin is one of the most delicate fabrics we know. It is extremely breathable, soft, and has a distinctive "waffled" texture that we love. The more you wear and wash it, the more substantial and pleasant it becomes for the skin.
-
Skin
HOW TO CAREGenuine leather is an investment for years to come. It is durable, authentic, and adapts better to you every day. To maintain its softness and deep color, it doesn’t require frequent treatments – just a little regular care is enough.
-
Sequins
HOW TO CARESequin clothing is our recipe for a spectacular look, but remember – it’s a material that doesn’t like haste or roughness. To ensure each sequin always reflects light just as beautifully, it’s worth giving them a moment of gentle care.
-
Acetate
HOW TO CAREThe acetate lining is the quiet hero of your wardrobe. It’s thanks to it that blazers and dresses drape so beautifully, don’t generate static, and are incredibly comfortable against the skin. Since this fiber is very sensitive to high temperatures and chemicals, it’s worth taking special care of it.
-
Gold-Plated Brass
HOW TO CAREGold-plated brass is a perfect duo – it combines the warm glow of gold with exceptional durability. To keep the gold plating pleasing to your eye for as long as possible, remember that jewelry, like your favorite clothes, loves gentleness and proper care.
