Uses USA sizing

Also labeled as: UK, EU, FR, AUS, JP

Wacoal manufactures some bras sized S/M/L

Uses UK sizing

This means that this brand at some point used some way to match their cups, from their main sizing system to other regions, for example:

UK	D	DD	E	F	FF
US	D	E	F	G	H

On this fictitious example, E cups in US correspond to DD cups in UK.

Later, at some point they decided to change how they do their cup conversions, in this case:

UK	D	DD	E	F	FF
US	D	DD	DDD	E	F

Note the introduction of DD, DDD cups shifting now E cups match to F cups.

Now, people that was buying by US sizes will now be confused on why things don't fit the same.
