I notice there's a mismatch between your product title (Costa Blue Top) and the instructions provided (white trousers, blue pinstripe, cotton). I'll create a description based on the instructions you've specified, as those appear to be the actual product details: Crisp white trousers meet timeless style with a sophisticated blue pinstripe pattern that works as hard as you do. Crafted from breathable cotton, these versatile bottoms transition seamlessly from office meetings to weekend adventures. The classic pinstripe adds just enough personality to keep things interesting, while the comfortable cotton fabric keeps you feeling fresh all day long. A wardrobe essential that proves sometimes the best pieces are the ones that go with everything.
