I love shopping! Now, anyway. I despised it prior to my starting to transition. But now I actually wear colors other than black, and I look forward to getting dressed and going outside.
Regarding men's pants, try 'relaxed' and 'loose' fit, they have more room for larger hips/thighs. It may take some time and experimenting to find the cuts that work for you. I had a lot of luck with Old Navy for that. I could never wear women's pants, they were never comfortable and never fit right, so I was always stuck in skirts. Meh. I've found way more latitude with men's pants.
