What are the guidelines?

• Choose the right size bra—a too-tight fit can disrupt blood flow and lymph drainage, raising risks like edema.
• Opt for cotton bras, which breathe better. Synthetics can trap heat and elevate breast temperature.
• Avoid underwired styles to prevent pressure sores.
  Note: Women post-breast surgery or breastfeeding to avoid engorgement are often advised to wear one.
