I would return them to the coordinator - with an explanation.
However, I would not say "these things smell" - even if they reek - because that puts people on the defensive.
You could say something like "My allergies started to act up when I opened the bag - there must be something in the fabric that is really bothering me - could you return these to the makers so they could wash them in a fragrance-free, hypo-allergenci detergent, press them, and then I would be happy to long arm them."
And stress that these tops MUST be washed/ironed or pressed/threads clipped before you will touch them.
You might also tell them because of your allergies/health that you have to be careful about what you can work on.
