Ami Paris Elasticized Trousers in Black. AMI is a brand influenced by multiple fashion capitals, including Paris, New York, and Milan, and it shows in this piece. These drop crotch pants are a modern take on the trousers originally worn by French-military recruits in the19th-century. Now a high-street fashion staple, this piece incorporates an elasticated waist and ankles, while two large side pockets adorn the front of the trousers with slit pockets on the back, completing the look.
