RDR Hats 5X Silverbelly in 7 1/8 or 57 cm

Worn once only - purchased at the CFR last year cost me $499 - beautiful hat and well worth the money but it's just a little tight for me now, not sure why, it was great for the day/night I bought it been sat on the hat holder for 8 months need to make room as I'm bound to buy more this year! Rodeo season is here time to Cowboy Up. Would swap for an AHC in 7 3/8
