Affordable: Pixies Doolittle/Logo T-Shirt ($20)
High-end: John Varvatos Rock Roll Star Tee ($78)
Underneath Cobain’s cardigan or flannel was usually a graphic tee. Some of his favorite bands included the Pixies — a band whose sound Nirvana admittedly copied on Nevermind — the Meat Puppets, REM, and The Melvins. You can pony up for vintage tees on eBay or Amazon, or you can find contemporary shirts at any online music vendor for a lot less dough.
