Yes she did, I was accually a little disapointed with Märthas wedding dress, especially the shiny fabric, and think she has made better clothes for Märtha both before and after, still she was a beautiful bride and certainly one of the most happy looking
Wenche Lyche started making clothes for Märtha around 2000-2001, at least according to the press, and that was when Märtha accually got some style
She also made one of my all time favourite royal dresses, the one Märtha wore for Haakons wedding. Wench Lyche really like to make clothes out of zippers, and the bolero she wore with the dress was made out of zippers, she also has a skirt made out of zippers. she also like korsetts like on the pink and brown dress and the peach one in denmark
Lyche, makes dresses, suits hats and acessories, she has made most of Märthas clothes for special occations the last years, however she was not guilty of the chicken dress in Spain
Vg has a little picture special about some of the dresses she has made for Märtha
