I write this as someone who gave up wearing jeans as they added too many pounds, but that said... re men's jeans (e.g., Levi, Lee, Wrangler) look for styles that are labeled "Loose Fit" rather than Relaxed, Slim, Boot Cut, etc. They are more generous. The shortest length I have found is 30" which is probably a bit too long for you, but hemming is pretty simple and cheap if you don't want to do it yourself. As for women's, I have found that the Lee brand for women (e.g., 20W, not just 20, etc.) with a regular style waistband, but with some stretch, are pretty decent and don't look to "gendered" unless someone examines the direction of the fly opening. I have short legs and the length works for me, without going to Petite - for which you have to pass up the "W" cut. I don't know if you're near a Kohl's, but they carry them and they're often on sale. Target also has a loose cut Wrangler "carpenter jean" that's pretty generous. There's no doubt that buying clothes when one is overweight is, imho, a huge pain in the a**, especially when one would prefer to buy men's clothing! Good luck!
