To ensure the best fit, it is recommended to measure your body accurately. Use a flexible measuring tape and follow these steps:

• Shoulder: Measure from the edge of one shoulder to the edge of the other.
  
• Sleeve Length: Measure from the shoulder seam to the wrist.
• Bust: Measure around the fullest part of the bust, keeping the tape level.
  

By following these guidelines, you can select the appropriate size for your shirt, ensuring a comfortable and flattering fit.
