I know both items, Gryffin!
The blazer worked well on my petite client, who also wears a lot of black and white. Perhaps more relaxed than the blazers you usually wear, and a nice way to change things up if you like the vibe
The oversized houndstooth is playful, and I like that part best! Going to look fabulous with your salty hair! The scrunched sleeves are handy too.
If those pants don't work out, may I suggest these. I got them in toffee and they are great. Soft and very comfy! Long inseams, though. Will need a hack.
