Open letters still work to get consumers what they want. Last August, freelance writer Jenni Avins penned a passionate plea  in New York magazine's The Cut blog, asking J. Crew to bring back its scoop back tank swimsuit. 
 "What I want is smooth, taut fabric that stretches from my shoulders 
over my chest and ribcage, with hip-high leg holes and an open back to 
expose my skin to sand, sunshine, and seawater. I want it available in 
evocatively named colors like hibiscus, marine, and bottle green (in 
black, it's simply unstoppable.)"
 The letter touched the fashionable heart of J. Crew creative director 
Jenna Lyons, who immediately responded, saying she'd see what she could 
do. A few months later Lyons announced the swimsuit return
 in a two-page New York ad with a sassy, handwritten note that reads, 
"Dear Ms. Avins, Your wish is my command ... within reason. XO Jenna."
It's an excellent example of a brand listening to and responding to the
 wishes of a loyal customer.
