subject is wearing a white shirt in a studio shot?  I seem to have 
problems with blowouts in/on parts of the shirt...

Possible causes include whiteners in the fabric itself, whiteners in
laundry detergent, and excessive UV from budget studio strobes and all
battery-operated strobes. 

Better studio strobes offer low UV tube options. 

You might try a UV filter on-camera, but that may not be adequate. 

When specific items of white goods are manditory (eg clothing
catalogs) it's common to arrange for non-brightener or water-only laundry.

Rosco also makes a UV filtering gel that you can use on the lights, 
it's about $7 per 17x22 sheet. Helps to prevent the "whites" from 
turning blue.
