I received a personal shopper request from Jim, He is trying to find some items for his 16 year old son who is 6’8″ tall. His waist is 34″ and inseam is 38″ with leg opening of 20″ or more. He wears a size 17 shoe (the reason for leg opening size). Items needed are mens pants in causal and dressy style and jeans in relaxed fit. His thigh muscles are large.
Tall Personal Shoppper Help:
The good news is that we have special sections of men’s tall jeans and pants categorized by inseam length. We are constantly updating these sections.

• Men’s 38″ inseam jeans
• Men’s 38″ inseam pants

Based on what you have asked for here are some hand picked items I would like to recommend:

If you want the perfect fit, you may consider getting a pair of custom made jeans with your son’s measurements.

Popular among teen, Buckle’s Seth Jeans in loose style with your size and a 20″ leg opening. Here’s the same style with a medium wash.

Classic style Eddie Bauer’s loose fit 5 pocket jeans are also available with a long-rise which is good for most tall guys.

You can’t go wrong with a pair of Levi’s jeans. I had Rochester Clothing measure the leg opening of this pair of Levi’s 550’s in relaxed and the leg opening is 20″. They have a 90 day return policy.

Rochester Clothing also measured the leg opening on this pair of Levi’s Open Rigid-Welder jeans and the leg opening is 20″.

I’m not having much luck with a 34″ waist in casual or dressy pants with a wide leg opening. The widest legs I can find in your size is the following 2 pairs. They both measure 18″ wide at the opening.

Rochester Clothing No Wrinkle Flat-Frong Twill Pants – more of a casual style. They are almost sold out.
