The everyday shirt. The Clerkenwell Tab Shirt is an Oliver Spencer favourite and a wardrobe staple. Featuring a slim, square collar that conceals an optional fastening tab, a soft one buttoned cuff and signature red bar-tacked button hole complete the subtle attention to detail that have become synonymous to Oliver Spencer. The Talcot cloth has a cotton and linen blend composition, which makes for a great light-weight and breathable shirt. The cotton has been woven together using different colours on the warp and weft, which makes for an interesting marl effect across the shirt.
