Is she British or just chose a British name? Her pictures make her look skinny but her website says 28 for waist.

Sometimes the Profile info is wrong, but it says "White, Eastern European." Great Britain is in Western Europe.

Providers often choose professional names that us Westerners can easily pronounce and spell.
