What is your price range? If you have $400-600 to spend you are definitely better off getting something outside of a ludlow. The construction is very poor for the price they charge. Look into MTM (made to measure). Indochino is currently running a sale. There are 3 piece suits on their site for $400 and if you measure properly, little to no alterations will be needed.
Thick As Thieves LA also does MTM, and their construction is top tier especially at only $500 a suit. However, their sizing on works for slim dudes. No bigger than a 42 chest.
If you feel uncomfortable about providing measurements, Suit Supply have great cuts off the rack and their in house tailor offers unbelievably great prices for any alterations that need to be made. Suits can be had for as low as $399.
Just my two cents.
