Stimma is an orange knitted necktie, with the usual bobtail. Sure, a potent enough colour in its own right, but if you really want it to pop it'll be sensational in combination with a cobalt blue suit. Want a softer contrast? Browns and beige are best friends with orange, and with a yellow linen it may even snap, crackle and pop and come to love.
I ordered two silk knit ties, excellent price/quality ratio. Now also in 7.5cm and 8cm widths, which is a big plus. Free and fast delivery, as always. Having tried ties from Berg & Berg and DLA, among others, I can also recommend Tieroomi.
