My fella is attending a murder mystery party thing and his character is a 60s male model - I have looked through ebay and tried googling but cannot find any decent pictures or places to buy such clothes - so any ideas are greatly welcome!!!
Try watching 'The spy that shagged me' and 'Goldmember' - James Bond spoofs with Mike Myers. Might be very helpful. As for the place to buy such clothes, I'd try the local second-hand store. It might take some patience, but you can find some truly authentic 60's stuff.
