In the first of the sheva brachot the seven blessings made at a wedding and at the festive meals during the seven following days we pay tribute to those who demonstrate that G-d "created everything with the capacity to glorify Him" by emulating the Creators role in bringing joy to a chatan and kalla. All the wedding arrangements for Adam and Chava were made by their Creator to bring them the ultimate happiness, and those who participate in the simcha of newlyweds are glorifying the Creator by following in His ways.
To this explanation of the blessing provided by Rashi (Mesechta Ketubot 8a) we may add what we find in our gemara. The Sage Reish Lakish quoted Rabbi Shimon ben Manasia as stating that G-d even acted as the hairdresser for the first bride. The passage (Bereishet 2:22) which speaks of the Creator "building up the woman" is interpreted by him as building up her hair in an attractive fashion before presenting her to her groom.
It appears that this approach is based on the position that Chava was not built from a rib but was completely formed together with Adam and then separated from him. Nevertheless, the term "building", points out Maharsha, applies to the curling of Chavas hair and serves as the basis for the ruling in Mesechta Shabbat that one who performs such a process on Shabbat is guilty of violating the law against construction on the Day of Rest.
