Here's a vocabulary/key expressions PPT. Includes 'trousers' and a small drilling/practice section. My co teacher helped me explain that in the anglosphere, 'gown' usually refers to an evening gown and not a hospital gown or a sleeved apron.
For the listening class, we played bingo with various clothes and the target sentence 'put on your ____, please'. We had to drill 'shirt' and 'skirt' a lot as students pronounced them almost interchangeably.
For the reading class, we played a Sparkle Die game. (I don't remember who made the template, sorry. I copied the dialogue from the CDs and added some random sentences) I'd recommend writing 'sparkle' & 'die' on the board, so you can give them a hint if they get stuck.
