Looking for something a tad smarter than a regular T-shirt to wear into the office as the weather heats up? The deep-placket top seems to be filling the spot previously filled by the polo shirt in recent years, as a smarter alternative to the T-shirt. Whilst being a particularly nasty word – a placket – the double layer of fabric holding buttons or poppers at the neckline of a shirt (clearly I’m on a mission to decipher obscure fashion terms this week!) adds a touch of grandad-shirt smartness to an otherwise basic top. As with the deep-V popularised by American Apparel, the current trend for plackets is depth. This enables you to stay buttoned-up at your desk whilst giving you the option to reveal your man-cleavage in the pub beer garden come hometime. And options are always nice.
