Righty, my thoughts on that design:
Again, I was thinking having bigger print on the back otherwise no-one will be able to see it. VODKA PRINCESS in capitals and really big, at the top of the back, then a gap and then a picture, gap, then "Mine's a Vodka and Diet Coke", gap then near the bottom "Butlins Bognor, July 2008". Can you make a mock-up like that? Basically the same layout I did but substitute the drunken smile for whatever pic we can use.
On the front, I plan to rip it right down the middle so could you do it with:
NIKKI (centred in caps)
Butlins Bognor
July 2008
On the left breast, otherwise it will get ripped up so no-one can see it!
If you like hun, let me know the website you mocked it up on and I will have a fiddle. If we are going for plain t-shirts I have found a few websites which could be possibilities too xx
