Not recommended for beginners these are serious bow ties which are made according to neck size and cannot be adjusted. The advantage is that there is no unsightly adjusting buckle so they are perfect for wearing with wing collars. This disadvantage is that they are even more tricky to tie but well worth effort if you can manage it. Made in England from 100% white cotton marcella. Buy them according to your collar size. If wearing a separate collar which is 1/2" larger than the neckband, buy the larger size. Sizes: 15" to 19"
