Select your "chest size" above and you'll see all suits with your size in stock. The retail industry has standardized the drop to be 6 inches with the most common jacket/pant combinations being size 40/34 and 42/36. This is a convenient way of shopping and saves time. Suits Outlets uses US standard men's size and all blazers and pants are true to size. All chest sizes come in three length: Regular, Long and Short. An easy way to explain the difference between "Regular", "Long" and "Short" is, for "Short", both the sleeves and length of the overall jacket will be 1" - 1.5" shorter than "Regular", and same applies to "Regular" vs "Long".
