Let's survive summer in linen.  It's a light and breathable fabric that will keep you cool and relaxed when the temps rise and the humidity sets in.  From linen shirts to pants - casual and dress pants - Q. Contrary has a great assortment.  Yes, linen will wrinkle but everyone knows that.  It's a compromise to being cool and not sweaty.  

If 100% linen isn't your thing, some brands I carry offer a linen blend.  From NN07 to David Donahue shirts.  If it's cotton linen or linen tencel, both great blends to keep you cool.
