La Brassiere () is a 2001 Hong Kong romantic comedy film starring Lau Ching-wan, Louis Koo, Carina Lau and Gigi Leung. The film was followed by a sequel, titled Mighty Baby, which was released in 2002. Plot The film's underlying plot is to create the "ultimate brassiere" for a Japanese company specialising in this undergarment, hence the fanciful title. Samantha (Carina Lau), who is managing the Hong Kong subsidiary of the company, is the project leader of this assignment and she appoints two zany but highly creative designers to aid her in that project, Wayne (Louis Koo) and Johnny (Lau Ching-wan). Johnny flirts with Samantha soon enough, being engaged in such a work, which he claims would assist in his creative powers although the story was more engaged in the humorous efforts in creating the bra. However, Samantha snubbed his overtures and their love affair remained in balance. Meanwhile, during the project various prototypes were tried and tested, but with appalling results. Apparently, Wayne and Johnny being both male were unable to realise the finer points of creating the undergarment. Lena (Gigi Leung), a lover of Wayne and also working on the project then got the inspiration that the "ultimate bra" is the one which incorporates the feeling a woman has when her male lover lovingly supports her breasts. Accordingly, the two designers created just such an undergarment and was approved by their Japanese employers.
