The former Only Way Is Essex star took to the catwalk to model some of her designs, promising something for everyone.
"I've got a bit of everything - I've got long dresses, I've got little short ones," she said. "I wanted to do a bit of everything for the summer."
Guests included Peter Andre, Kerry Katona, Nicola McLean and Childs's cousin and former Only Way Is Essex co-star Harry Derbidge.
Speaking about recent rumours that she and Derbidge are to film a UK version of Paris Hilton's The Simple Life, the 21-year-old promised to take the socialite out in Essex when she is next in the country.
Childs added: "She's coming down to London in a couple of months and we'll definitely go out, 100%. I'll take her to Nu Bar, in Loughton, and then I'll take her to Sugar Hut. She's got to have an Essex night out. Oh my God, she'll have an amazing time."
Writing afterwards, she told Twitter followers: "Thank you to everyone that come to my launch tonight, I'm so glad everyone loves my collection, exciting year coming up. (sic)"
Impressed with her friend's collection, Katona tweeted her congratulations to Childs: "omg amazing babes well done you darling very proud xxx."
