Unlined Full Coverage Bra

Using a soft measuring tape, measure all around your rib cage, right under your bust. The measuring tape should be snug.

In the chart above, find the band size that corresponds to your rib cage measurement. For example, if you measure 32 inches under your bust, you should be comfortable in a size 36 bra.

Measure your bust at the widest part. Here, the measuring tape should not be too tight.This measurement will be more accurate if you take it while wearing a lightly lined bra that fits you well (avoid wearing a push-up bra at this step, because it would skew the result).

In the size chart column corresponding to your bra band size, find your bust measurement. For example, if your bra band size is 36 and you measure your bust at 39 inches, your bra size is 36C.

Using a soft measuring tape, measure your bust at the widest part.

Measure your waist at the narrowest part. That is usually around the same height as your belly button. At this stage, the measuring tape should not be too tight and should allow you to be comfortable.
