Dress Shirts & Blouses
Formal and business casual shirts and blouses for work and special occasions, often featuring wrinkle-resistant or 'no-iron' finishes.
Why It Matters
Wrinkle-free and no-iron dress shirts are treated with formaldehyde resins - a known sensitizer and carcinogen. Non-iron shirts can have formaldehyde levels that cause skin reactions. Work shirts are worn for 8+ hours daily.
