A suit may not work for everyone's lifestyle, but it's a good idea to have at least one in your wardrobe so you're ready for the unexpected job interview or other conservative affair.
While everyone may not have a reason to wear a full suit often, you can easily wear the pieces as separates. A suit jacket can add polish and sophistication to a button down shirt and jeans and it can replace a jean jacket when you want a piece that has more elegance. You have endless options to pair with the jacket, pants or worn all together whether it be button down shirts, ultra-feminine tops, camisoles, sweaters even t-shirts.
Look for a classic neutral color in an all-season fabric. Bring it to your tailor to ensure the perfect fit. And always remember to launder both pieces together to ensure that one doesn't fade faster than the other.
