Step 1: Measure first, brand chart second
Get your true under-bust and bust measurement, then check each brand's size chart โ they all differ.
Step 2: Read reviews for fit notes
Reviews are gold. Look for "runs small" or "band loose" comments and adjust your order.
Step 3: Buy 2 sizes when in doubt
Buy your true size + sister size. Return whichever does not fit.
Step 4: Always check the return policy
Most lingerie brands accept returns on unworn (tags-on) bras. Some specialty brands offer free fit-exchange.
