The distinct smell of Shein clothes usually comes from chemical residues left over from fast manufacturing and shipping processes.
The Source of the Smell in Shein Clothes
Shein is one of the fastest-growing fast-fashion brands worldwide, known for its trendy, affordable clothing. However, many customers notice a peculiar and sometimes unpleasant odor when they first open their Shein packages. This smell often raises questions about the product’s quality and safety.
The primary cause of this odor stems from the manufacturing process. Fast-fashion brands like Shein produce garments at an extremely rapid pace, often using synthetic fabrics treated with various chemicals. These chemicals include dyes, formaldehyde-based resins, finishing agents, and solvents used to keep clothes wrinkle-free during transport.
Because Shein ships products directly from factories in China or other low-cost production countries, garments often sit in sealed plastic packaging for extended periods. This sealed environment traps volatile organic compounds (VOCs) emitted by these chemicals, resulting in that distinctive “new clothes” smell — but amplified and sometimes unpleasant.
Common Chemicals Responsible for Odors
- Formaldehyde Resins: Used to prevent wrinkles and mildew during shipping; known for a strong chemical odor.
- Dyes and Pigments: Synthetic dyes can release odors due to chemical residues.
- Solvents and Finishing Agents: Applied during manufacturing to provide texture or water resistance; these evaporate slowly.
- Plastic Packaging: Seals VOCs inside, intensifying the smell.
These chemicals are generally within legal limits but can cause discomfort or allergic reactions for sensitive individuals.
How Fast Fashion Influences Clothing Odors
Fast fashion thrives on speed and volume. Brands like Shein prioritize rapid design-to-delivery cycles to keep up with trends. This approach affects every stage of production:
1. Mass Production: Large quantities produced quickly with minimal quality control.
2. Chemical Use: Heavy reliance on synthetic fibers and chemical treatments to reduce costs.
3. Packaging: Clothes tightly packed in plastic bags to save space during shipping.
4. Shipping Time: Long transit times combined with sealed packaging allow chemicals to accumulate.
Because of these factors, garments often retain strong chemical odors when they arrive at customers’ doors. Unlike higher-end brands that may use more natural fibers or wash garments before shipping, Shein’s business model does not prioritize odor removal.
Fabric Types and Their Role in Odor Retention
The fabric composition greatly affects how much odor a garment holds:
- Polyester and Nylon: Synthetic fibers absorb and retain chemical smells more than natural fibers.
- Cotton Blends: Less prone to strong odors but still affected by finishing agents.
- Rayon/Viscose: Semi-synthetic fibers that can retain smells due to chemical processing.
Shein’s heavy use of polyester blends contributes significantly to why their clothes smell strongly out of the package.
How to Remove or Reduce the Smell from Shein Clothes
If you’ve received a package smelling like chemicals, don’t worry—there are several effective ways to minimize or eliminate the odor before wearing your new clothes.
Washing Techniques
Washing is the most straightforward solution:
- Use cold or warm water with a gentle detergent designed for synthetic fabrics.
- Adding white vinegar (about 1 cup per load) can neutralize odors naturally.
- For stubborn smells, soak clothes in a mixture of water and baking soda for 30 minutes before washing.
Avoid hot water as it may set some odors permanently into synthetic fibers.
Air Drying vs Machine Drying
Air drying outdoors is ideal because fresh air helps dissipate trapped VOCs quickly. Sunlight also acts as a natural deodorizer but avoid prolonged exposure if colors might fade.
Machine drying can trap odors inside fabric if not fully ventilated afterward. If you use a dryer, add dryer sheets with neutralizing scents or essential oils like lavender for freshness.
Additional Deodorizing Methods
- Hanging clothes near activated charcoal bags absorbs moisture and odors effectively.
- Spraying diluted fabric fresheners or vodka sprays can break down residual chemicals without leaving heavy fragrance.
- Ironing with steam helps release trapped chemicals from fabric fibers.
These methods combined will significantly improve your experience with Shein clothing items.
Health Considerations Linked to Clothing Odors
Strong chemical smells on clothing aren’t just unpleasant; they can pose health concerns for some people:
- Skin Irritation: Residual formaldehyde resins may cause itching or rashes on sensitive skin.
- Respiratory Issues: VOCs released into the air can trigger headaches, dizziness, or breathing difficulties in susceptible individuals.
- Allergic Reactions: Certain dyes or finishing agents are known allergens that could provoke reactions after prolonged skin contact.
While most users tolerate these odors without serious effects, it’s wise to wash new garments thoroughly before wearing them close to your skin—especially if you have allergies or respiratory conditions.
Comparison: Shein vs Other Fast Fashion Brands on Clothing Smells
Not all fast-fashion brands produce garments that smell equally strong out of the box. The following table compares common factors influencing clothing odor across popular brands:
| Brand | Chemical Treatment Level | Typical Odor Intensity |
|---|---|---|
| Shein | High – heavy use of resins & synthetic dyes | Strong chemical smell common upon arrival |
| Zara | Moderate – uses some natural fibers & pre-washing steps | Mild odor; usually fades quickly after washing |
| H&M | Moderate – mix of synthetic & organic materials | Mild to moderate; depends on fabric type & batch |
| Boohoo | High – similar fast production methods as Shein | Moderate to strong; varies by product line |
This comparison highlights how manufacturing choices affect odor presence across brands competing in the same market segment as Shein.
The Role of Packaging in Amplifying Clothing Smells
Packaging plays a surprisingly big role in why new clothes sometimes have strong smells. Most Shein products arrive vacuum-sealed in plastic bags designed for compact shipping efficiency. This airtight environment traps volatile compounds emitted by treated fabrics without allowing proper ventilation.
Over time—sometimes weeks—the trapped VOCs build up inside these packages until opened by the consumer. The sudden release leads to an intense burst of chemical aroma that feels overwhelming compared with other shopping experiences where items come loosely packed or pre-washed.
Consumers who want to reduce this effect should immediately remove garments from plastic packaging upon arrival and allow them time outside sealed bags before wearing or washing them.

Frequently Asked Questions
Why Do Shein Clothes Smell When First Opened?
Shein clothes often smell due to chemical residues from the fast manufacturing process. These chemicals include dyes, formaldehyde resins, and solvents used to keep garments wrinkle-free during shipping.
The sealed plastic packaging traps these volatile compounds, intensifying the odor when you first open the package.
What Chemicals Cause the Smell in Shein Clothes?
The smell is mainly caused by formaldehyde-based resins, synthetic dyes, and various finishing agents. These chemicals are used to preserve the clothes during transport and maintain their appearance.
Though generally within legal limits, these substances can emit strong odors that some customers find unpleasant.
Does the Smell of Shein Clothes Indicate Poor Quality?
The odor does not necessarily imply poor quality but reflects fast production methods and chemical treatments. Shein prioritizes rapid manufacturing and shipping, which involves heavy use of synthetic chemicals.
Many fast-fashion brands have similar issues due to mass production and packaging practices.
How Long Does the Smell Last on Shein Clothes?
The smell usually fades after airing out the clothes for a few days. Washing the garments before wearing can also help remove residual chemicals and reduce odors effectively.
Ventilation breaks down trapped volatile compounds responsible for the smell over time.
