Whenever Taylor Swift steps out wearing something cute that doesn't cost thousands of dollars, fans know they have to act fast. The mega pop star has a habit of selling out items in minutes, which is probably why her recent look - a pinstripe tank dress - has been flying off the shelves. The Staud design, priced at a reasonable (for Swift) $325, is already gone at Nordstrom, and key sizes are missing from the brand's site, leaving Us in the ultimate fashion girl pickle. The breezy piece, which Swift sported while out in New York City on April 27, is no doubt ideal for spring.
