Yeah, $100 a shirt is fairly competitive with other fashionable brands.

I end up buying more expensive shirts just because I don't feel as bad about having to have them altered. My arms are really long and my neck/shoulders are really broad relative to my height, so even slim or "extreme slim" dress shirts have a tendency to billow out of my pants unless I have them taken in, and I always have to have the arms slimmed significantly as well. When you spend that kind of money to have the clothing altered, you might as well spend a little extra to alter nicer clothing.

Take a look at TMLewin and CTShirts. I think they offer the best value in shirts. Spending more than 60$ on a shirt is not necessary.

I don't know about US, but in Spain you can get a tailor made shirt for 100$.

CT definitely offers some of the best deals. Kamakura offers extremely high quality shirts for $89, though. Bonobos is just not high enough quality to support the hundo price point.

Actually, you're right. Most of my shirts were on sale, and ended up being about $100 after alterations.
