Hi there, and welcome to our little family!
When I started my transition, I did a reconnoissance mission of the men's departments of all the big clothing retailers so I could figure out what sort of styles I like and who stocks stuff that fits me. I'm pretty much the same size as you and I have no trouble getting jeans etc. in my size, including skinny jeans.
I could offer recommendations about where to shop but it's difficult to know whether they'd be useful without knowing where in the world you are. Susan's has members from every inhabited continent so perhaps it would help if you mentioned which country you're in, and then I'm sure some recommendations will come in. I'm guessing you're somewhere in North America because you've referred to trousers as 'pants'.
One good tip is that men's trousers tend to be measured in leg length and waist width. At your height your leg length is about 28-30 inches so you can try jeans in those sizes; but don't use your waist measurement because cis guys don't tend to have any major difference between their hip & waist sizes, whereas we of course do so our hips tend to be much wider than our waists. So instead, measure the widest part of your hips and use that for the 'waist' measurement in men's trousers.
You could then select trousers in those sizes & try them on in the changing rooms. If you don't pass as male or are worried about using the men's changing rooms, simply grab the trousers you want from the men's section, and try them on in the women's section.
And if you want to avoid a VPL under your clothing, you might want to try hipsters instead of boxers. There are some styles that don't have seams, and they don't show at all under even the tightest jeans.
