This suit I believe is orange.
His fancy red suit with an obvious 'flower leaf' design, it resembles vines as it climbs up his collar and wraps around his arms. This suit, like all of the higher class suits, has buttons that match the ones on the coat traveling down the side of his pant. This suit also has a 'bell bottomed' look. I assume his pants have white material in the 'v' split at the bottom of his pants.
In the below picture, one can easily see the silver buttons and beautiful trim design. This vest also ends in a 'V', lapping over a short amount. His trim appears to be quilted on.
The buttons and trim travel down his leg.
Orange Suit
Don Alejandro wears his Orange suit quite often, as all the costumes are mostly the same, I shall only point out interesting details of the suit.
Though the picture is blurry one can still the the flower like trim, the white, lacy undershirt and black tie. He also has a very pleasant looking beard.
Note that the all three black suits above are different.
