Right, so everyone needs a really decent white tee in their wardrobe, and this one from Polo Ralph Lauren is pretty much spot on. It's proper pure cotton, so it feels super soft against your skin and lets you breathe, which is exactly what you want for wearing it all day. The 'Classic Fit' means it's not going to cling or look baggy; it's just that perfect, easy shape. You've got the short sleeves and a simple crewneck, which makes it dead easy to throw on. Oh, and obviously, that little embroidered pony on the chest gives it that recognisable branding. Honestly, you'll be reaching for this constantly. It's brilliant for just chucking on with jeans or chinos, or you can even layer it under an open shirt or a blazer if you're trying to look a bit more put-together but still keep it chill. It's one of those pieces that just works, whatever you're doing.
