WTB small cream/tan LS button-up shirt, point collar (button-down possibly)

I am trying to find a shirt to go with a dark navy linen double breasted suit. I am thinking off-white/tan/ivory/cream, point collar (possibly button down). I generally wear small. Neck size is 15.75, ideally for a slim build with broad shoulders but if it's close I can get it tailored. Fabric-wise, I'm open to suggestion, but given the suit is linen it should complement that and not repeat it. It's for a wedding... mine! Kind of. Small wedding in COVID, we're finally throwing a party. So, formal, but I have some flexibility.

Apologies if I'm posting a WTB incorrectly, new member to style forum!

If you have a solid red/burgundy tie to go with it, let me know!
