Huzzah! Stretching has been adequately carried out (I rekkon I may have got an extra size out of it). I melded suggestions from here, Ben and the ever lovely CBBers and came up with a solution which appears to have worked (boobs no longer squashed, tummy lumps less obvious and the feeling of being put in a straightjacket lessened!)
For those of you who find that you need to do a similar thing in future, here is how the great achievement was won ;)
Basically the tshirt was well soaked in the bath and then wrung out so it was damp. Then we used a coathanger for trousers a bit like this one
(except the cheap crappy asda equivilent which meant the edge of the tshirt had to be turned over a couple of times to get it to grip properly) on one of the side edges and hung it from the bathroom door.
On the other side edge (now at the bottom) we put another of those coat hangers and from the bottom of this (the part that usually hooks over the clothes rail) we hung a carrier bag from with a litre carton of OJ in it.
We left it to dry and then repeated it in the morning so in all it had about 24 hours on the rack.
In the end the TV Crews and photographers from the local rags came in and did their thing (there will be more tomorrow when clearing is actually open including possibly some of the national papers) and I was interviewed by BBC Radio Kent. No idea when/if I'll be on, but if you're in the area and you hear a clearing opererator named "Elizabeth" talking then that's me! All this in the name of corporate publicity for the university (who decreed the tshirts had to be visible all around *sigh* so the people under the aircon froze and people who didn't fit into the tshirts properly and hadn't stretched them looked uncomfortable)!
I'm so relieved it's over and thankful to all of you who commented on my last post
I cannot even express it :D
