As the table shows some fabrics are better adapted for this or that season. Linen and cotton are materials to be used in summer, while silk is a fabric comfortable to wear in both seasons. Wool can be used both in winter and summer depending on its quality (which will be presented below).


Which quality of wool to choose?

It is important to note that wool is a fiber of animal origin: sheep, lamb, etc. After shearing and scouring the fiber undergoes a process called carding to separate and then intermix the fibers. The carded wool yarn can be made into fabric using a plain, satin or twill weave. The resulting fabric is thick with a raw appearance and is suitable for winter apparel.

The carded wool intended for worsted yarn then undergoes the gilling and combing process. This process removes short fibers and places the longer fibers parallel to each other, to give combed wool. Worsted yarn can be made into fine fabrics with patterns using a plain, satin or twill weave. The result is a smooth, more durable fabric. Combed wool is suitable for winter or summer apparel according to the fabric’s thickness.

There is a specific wool classification called the "super". The super number provides information regarding the quality of wool according to the fineness of the fiber. So, the finer the fiber, the bigger its super number. The number following the term Super determines the number of woven fibers per square centimeter. The diameter of the fibers is measured in microns. The International Wool Textile Organization has codified supers as follows (excerpt):


Quality Diameter of the fibers
Super 80's 19,75 μm
Super 90's 19,25 μm
Super 100's 18,75 μm
Super 110's 18,25 μm
Super 120's 17,75 μm
Super 130's 17,25 μm
Super 140's 16,75 μm
Super 150's 16,25 μm
Super 250'S 11,25 μm


From this ranking, it is generally accepted that the higher super number the fabric is given, the finer, the more fragile, the more flexible it is:

o Fabrics classified below the Super 150's are considered thick, sturdy and resistant (Super "fine")

o And above as fine, fragile and fluid (Super "superfine")

o A super "fine" fabric would be ideal for an everyday outfit.
