$50 is a hard spot. I'm not aware of anything other than Lands End and maybe Brooks Brothers on sale that's in that spot, and to my knowledge, they don't have a lot of wedding ties.
At the $75-$80 range, Kent Wang, Howard Yount, and Sam Hober are the standards. Sam Hober has several good wedding tie patterns, including several Glen Plaids in different scales.
Yeah I hear you. I rather like Kent's stuff. The issue is the cumulative impact on my wallet of not only the tie, but also the cuff links I'm going to be doling out to these guys.
