It is not often that you can find a better selection on tall sizes than normal sizes but that is exactly what you can find at Orvis right now! This is classic clothing rather than "on trend" but with up to 50% reductions on some classic men's items, it is well worth a look!
Orvis is well known for its outdoor and sporting clothing and it is one of few mail order / internet companies to offer tall sizes. Tall sizes offer an extra one inch on sleeves and 1.5 inches on the length of the classic fit shirts and polo shirts. These will suit most builds although maybe not so suitable for the tall and particularly slim since the classic fit is quite roomy.
Right now, their class polos are on sale (50% off) in around seven colors in Medium Tall and Large Tall sizes. There are also cotton twill shirts for around 40% off with a few different styles.
