Cotton is a natural fiber widely used in clothing, bedding, and household textiles. It is known for being soft, breathable, and comfortable against the skin. Cotton can be used on its own or blended with other fibers to change how a fabric feels, stretches, or wears over time.
Also Called
- Cotton
- Organic cotton
- Combed cotton
- Ring-spun cotton
- Mercerized cotton
- These are all still cotton, but they may be processed differently.
Common Use
Cotton is commonly found in:
- T-shirts
- jeans
- button-up shirts
- sweatshirts
- underwear
- dresses
- jackets
- socks
- towels
What It Does
Cotton is valued for comfort and breathability. It usually:
- feels soft
- allows airflow
- absorbs moisture
- works well for everyday wear
- feels less synthetic than polyester-heavy fabrics
Depending on the weave and weight, cotton can feel light and airy or thick and sturdy.
How It Affects Fit
Cotton usually has little to no stretch unless blended with spandex or another elastic fiber. This means:
- 100% cotton garments often rely more on cut than stretch
- flat measurements are usually more literal than with stretchy blends
- cotton can shrink if washed or dried with high heat
- a garment may fit differently over time if it has been repeatedly dried hot
This matters a lot with secondhand clothing. A shirt tagged large may measure closer to a medium if it has shrunk.
Common Fabric Blends
Cotton is often blended with:
- spandex
- polyester
- rayon
- linen
Examples:
- 100% cotton
- 98% cotton / 2% spandex
- 60% cotton / 40% polyester
- 55% cotton / 45% rayon
Pros
- soft and comfortable
- breathable
- widely available
- usually easy to wash
- common in everyday clothing
- tends to feel familiar and non-slippery
Cons
- may shrink with heat
- can wrinkle easily
- may fade over time
- absorbs moisture and can feel heavy when wet
- some cotton garments lose shape faster than synthetic blends
Washing and Care Notes
Cotton is generally easy to wash, but heat matters. High dryer heat can shrink cotton and make garments shorter or tighter than expected. Dark cotton pieces may also fade with repeated washing.
Thrift Notes
When buying secondhand cotton clothing:
- check for shrinkage, especially in length
- compare actual measurements instead of trusting the tag
- look for fading, thinning fabric, and stretched collars
- inspect underarms, knees, elbows, and seat areas for wear
- remember that older 100% cotton garments may fit differently than newer stretch blends
Why It Matters for Sizing
Cotton is one of the most common reasons a tagged size does not match actual measurements. A 100% cotton garment may have shrunk from washing and drying, especially if it was exposed to high heat. This is why actual measurements matter more than the tag alone.
