Thanks to its innovative fabric construction, our performance flex jersey offers a great deal of flexibility and freedom of movement. This allows us to create the perfect fit that is close-fitting but not restrictive.
Our multidirectional stretch ensures high dimensional stability and resilience, which prevents wear and creasing in the long term.
The combination of ultra-fine microfibers with Lycra makes the fabric particularly lightweight. In combination with a special knitting technique, the fabric always remains particularly smooth, making it ideal for traveling and on the go.
This is how your jacket is constructed.
Reinforces fine fabrics and shapes a natural breast form. Over time, this insert adapts to your body and gives you a unique fit.
A precisely coordinated arrangement of natural fabric layers that forms a stable chest and shoulder structure.
This inner finish preserves the natural shape of the breast with a perfect drape.
The high-quality inserts are light as a feather, comfortable and give the jacket volume.
Alle IOS Produkte bieten dir maximalen Komfort, moderne Schnitte und besonders hochwertige Qualität.

The jacket has a modern, more body-hugging fit.
Use your usual jacket size as a guide and check the notes on the product page. The modern slim fit fits cleanly at the shoulders and remains comfortable in the torso. If you are wavering between two sizes, opt for the larger size. Feel free to use our size finder on every product page.
For a classic look, navy, dark blue, dark gray or black are a safe choice.
If the dress code is conservative, many people go for navy or black because it looks calm and professional. Beige or light gray bring a little freshness, but remain serious. Forest and light brown work well for smart casual and can be combined with a shirt or fine knit. Choose the color that is easy to combine with your shoes and pants.
Yes, both the jacket and the trousers are made for everyday comfort.
The styles combine a modern fit with freedom of movement so that you feel comfortable in the office, at appointments or on the go. The fabric is comfortable to wear and is designed for easy care. This makes the suit suitable for long days without much effort. It doesn't crease and always keeps its perfect shape without wearing out. A comfortable slim fit suit that always makes you look and feel good.
You choose the model, color and size, add it to the shopping cart and go to the checkout. Returns and exchanges are quick and easy via our returns portal.
In the checkout, you will see the available shipping options and payment methods. After placing your order, you will receive a confirmation and can contact support if you have any questions.
If something doesn't fit, you can exchange it for the right size free of charge or simply return it.
Hanging and airing is usually sufficient.
After wearing the jacket, hang it on a stable hanger, gently smooth out any creases and air it briefly. Store it in the wardrobe with some space to keep its shape. Check the care instructions before cleaning. When traveling, a light cover helps to ensure that the jacket arrives protected.
The jacket should always be dry-cleaned according to the care instructions. The trousers, on the other hand, can be washed easily in the household wash according to the care instructions.
Yes, the IOS SUIT is the perfect wedding suit if you are looking for a very comfortable slim fit suit for your wedding.
The IOS SUIT is also perfect as a guest at a wedding, as it is smart but not overdressed. You'll feel comfortable and look good!
Decide according to the occasion, your style and the pieces you already wear.
Navy and black are very versatile and go with most business outfits. Beige and Light Brown add summery warmth to your look. Petrol Blue and Forest add a modern accent but remain understated. Take a look at the pictures on the product page and choose the suit that is easy to combine with your shoes and shirts or simply the one you like.
