For those who have never heard of her, Ms. Tuttle is a New Age practitioner who is heavily involved in both New Age and occult activities. She bills herself as a certified Master Rapid Eye Therapist, a Reiki Master Teacher, certified Energy Medicine and Emotional Freedom Technique Therapist.
Being deeply involved in New Age "energy", it's no surprise that her "Dress Your Truth" course is based on determining a person's "specific energetic movement" along with personality characteristics and facial features.
She's also a proponent of Rapid Eye Therapy or RET which is allegedly "a natural, safe way to release stress and trauma" that opens up neuropathways where "energetic memories" of personal and inherited trauma is trapped. She cites examples such as a memory of being trapped in the birth canal or in a relationship.
"We believe neurons in the brain stem switch on the same way they do in REM sleep, causing communication at the cellular level throughout the body. Energy confined at the cellular level by emotional or physical trauma is thus accessed allowing energy discharge through a fast eye blinking process. Clients release issues and emotions at a comfortable rate without reliving incidents."
This might sound authentic, but her site offers not a single peer-reviewed clinical trial to support any of these claims.
She's also a Reiki master, the dangers of which are explained here.
In addition to the above, Tuttle also practices the Emotional Freedom Technique, which is described here, and also has little or no scientific backing.
In summary, there is nothing being sold by Ms. Tuttle that actually works, or that doesn't involve a New Age belief of one kind or another. I would avoid her ministry and product line.
