It took me 3 months to find a good pair of cotton slim fit khaki pants and I love this pair from H&M! They're perfect for summer, pair it with a dress shirt, or t-shirt, or polo...they literally go with anything!
BUT, this pair of pants in this cotton is a nightmare to wash and iron, it wrinkles so easily and so intensely. I'm sure many others on this website have similar experience with cotton before.
Oh, and my favorite part of the outfit is actually the Jack Spade tote/messenger bag, hehe.
