Overall, I decided that Cool Nights was the wrong profile for me. I chose it mainly because many of the pictures showed solid color shirts in bold colors, which is something I like. But the description says that "The Cool Nights selection can be described as going-out clothes with a youthful flare." But I don't do very much going out, and while I'm interested in an update to my wardrobe, "flare" is not what I'm looking for.
So I decided to switch over to Tomorrow's Boss for my next shipment. The description still mentions "youthful flare" (it looks like they didn't break the bank on their writers), but it also talks about building "sharp wardrobe for a day in the office or a night out." That's definitely more of what I'm looking for; from what I can see, the styles are not too conservative, but I don't think I'm likely to get loud patterns from this collection.
