Wow this suit exceeded my expectations! The sizing chart was accurate and the fit was great. The material felt soft, smooth, and surprisingly high quality it honestly felt much more expensive than the price we paid. I also liked the ample amount of pockets inside the blazer. Overall, a great value and perfect for a polished look without spending a lot. Highly recommend!
