If you have a garment steamer, they are great for eliminating the type of smells that seem to inhabit garments that have been stored for a long time.

Febreeze (from Coles) is quite a good product, especially if followed up with the sunlight and fresh air option,treaing both sides of the garment, and regularly turning it inside out and back again. A lot can depend on how robust the item is.

Good luck,

Marina.
