we are off on holiday next thurs and I have just realised ds's swim T-shirt is too small. He is red head and burns so it is essential holiday wear.
I don't want to buy on-line as the sizes are always hopeless on swim Ts (his current one is officially 2 sizes bigger than normal clothes and is too small)
Any ideas where I can get one? Problem is I need size 12 ish and most only do them for little kids. Also don't want to spend a fortune 
don't really know where to start, I always grab them when I see them in end of year sales and stuff.
Thanks in advance
