I am Marty, a sewing pattern with multiple possibilities, 150 exactly! Yes, I can be sewn in 150 versions thanks to my different styles, collars, sleeves, lengths, button plackets… I can either be a tiered top, tunic or dress, and even a curved hem top or dress. I have 5 sleeve options: sleeveless, short sleeve, shirt sleeve and 3/4 sleeve or long sleeve with elasticated cuff. I have 3 different collars: Mandarin collar, shirt collar, and double shirt collar. I also have 2 buttoning options: polo style button placket or a classic button placket (partial or full length).
With my endless possibilities, you can wear a different version for all occasions, all seasons, all eventualities.
