Fh/bm ties

I am trying to find a tie for my FH and his BM and had the idea of trying to find something that pseudo matched my future daughter's flower girl dress. She'd get a kick out of matching her dad. But I haven't really found anything like her dress below. The closest I found had a black background, but he's wearing light grey pants and vest. Not sure what his brother/BM is wearing, but I'm going to push for similar. It's an outdoor garden wedding in July in NJ, so I suggested not wearing jackets. I don't want heat stroke on our wedding day.

So I just a crazy idea of trying to DIY the 2 ties. I found instructions online and they don't look very difficult. I don't sew a lot, but in my past I've made full-length, long-sleeved dresses with pleats/gathers. Much more complicated than a neck tie. And my mom has sewed my whole life, so I could ask her for help if I got stuck. I was thinking I could just buy 2 of the dresses (they're about $30) and use one to make the ties.

I don't really want to do it. It's not a saving money issue. I just can't find any ties that look anything like the FG dress. And I'm pushing for that. It doesn't have to be an exact match, but I can't even find similar. Has anyone else made neck ties?
