Anais Plunge Bra Powder

Tips for Determining Your Best Size:

Read Reviews Carefully: Pay attention to reviews from people who mention their usual bra size and how the Anais fit them. Look for patterns.
Consider Your Breast Shape: As mentioned, fullness and shape matter.
Journelle's Size Chart: While not always perfect, consult Journelle's size chart for their general recommendations.
Try On Multiple Sizes (If Possible): This is the best way to guarantee a good fit. If ordering online, check the return policy.
Sister sizes: Remember that a 36B has the same volume as 34C and 32D.
If You're Between Sizes:

Err on the Side of Larger: It's generally easier to adjust a slightly larger bra (e.g., with tighter hook settings) than to make a too-small bra work.
Prioritize Band Comfort: A snug but comfortable band is crucial for support.
In summary, due to its design, the recommended is to increase the band number. If you have a fuller breast, you should also consider increasing the cup letter. If you have a shallow breast, consider decreasing the cup letter, after having increased the band number.
