The reality TV personality wore a white Jeanette dress from her range retailing at £80 to the event at The Millennium Hotel in London yesterday (September 12).
Childs's collection consists of 17 new pieces with prices starting at £55.
The Celebrity Big Brother contestant tweeted before the photocall: "Big day today , getting ready to launch my autumn winter collection, looking forward to meeting all the buyers that wholesale my clothing."
In the past month, Childs has also launched her debut perfume, promoted her swimsuit range and opened her own boutique.
Speaking at the ribbon cutting for her Brentwood, Essex establishment, Childs commented: "My clothing line has obviously gone mental in this past year and I just can't believe people are so interested in what I'm offering.
"My website crashes all the time, and people are always on it, so I thought, 'Why not open a boutique?'"
