Final answer:
To avoid foundation transfer onto clothing, use translucent powder to set the foundation.
Step-by-step explanation:
To avoid the transfer of foundation onto a client's clothing, you can set the foundation using translucent powder. Translucent powders are colorless powders that help to set makeup and create a matte finish without altering the color of the foundation. They help to absorb excess oils and prevent the foundation from smudging or transferring onto clothing.
Setting sprays are also commonly used to set makeup, but they may not be as effective in preventing transfer onto clothing as translucent powder.
Loose powder is a type of translucent powder that comes in a loose form, while blotting paper is used to absorb excess oil and shine throughout the day, but it may not be as effective in setting the foundation to avoid transfer.
