Help me find some T-shirts

[RidingInTheMidnightBlue]

After a very tiresome trawl around the high street, and a quick scout online, I'm beginning to despair. I'm heading to tropical climes at the end of the month and need T-shirts to wear with denim shorts, skirt and skinnies. I'd like them to be less than £30 (ideally much less), 100% cotton, not breton style (I have one like that), not white, black or orange. I'm in my 30s so nothing too teeny.
Please help!

the only ones that I have found that are stylish are from uniqlo but they are not 100% cotton but they fit well are exceptionally reasonably priced and wash well.

I agree that uniqlo is great for tshirts.
I also love some of the American brands (splendid etc) but they are very expensive.

american apparel have tons

Thanks all, went very mumsnet and got 3 at Boden.
