I'm very fond of red and camel worn together. If you have any of this year's caramel, consider pairing these colors. The new caramel is such a rich tone and complimentary with your gray and black pants too.
I like the longer open front cardi, which Louis featured again last night, in caramel paired with a tie front blouse I own in a soft black and white vertical print with the red pants. I can accessorize with red, caramel, (British tan or saddle works well) or black.
You mention the velvet top, are you looking for a dressier outfit or just considering a column of color due to your height? I'm under 5'2" and break up colors and wear one top to bottom, each successfully. Personally, I like to frequently match my shoes to my pant color to avoid that break which can cut the visual line at the ankle. There's so much you can do with the red pant, please feel free to share any other specifics you have in mind, ie casual to dressy. We're full of ideas you might like. Shop your closet too. ♡♡♡
