My sister has requested "nice t-shirts with a really simple shape" for her birthday. She is v stylish and usually into labels I have never heard of so wondering if any similarly sartorially blessed Mumsnetters can tell me where all the cool, hip, quality loving people shop for theirs please? My sister tends to get her stuff from a mixture of Liberty and achingly hip pop ups in London. I know I can ask her but I'd love to surprise her with something perfect!
