Finding the perfect jeans is so so hard. Sometimes you have to try several cuts across different brands before you find ones that work - especially if you are difficult to fit. I haven't fit jeans off the rack since I was a kid. My build is such that SOMETHING in them needs to be altered, always. And different cuts fit differently than the label often says - some skinnies are too tight; some straights are too skinny; some bootcuts are too flared. My wise tailor says, find ones that fit your widest point - the rest can be adjusted.
Take your measurements, or have someone take them for you. Waist, upper hip, lower hip, thigh, calf, ankle opening, inseam. Use those measurements when you shop. Book an appointment with a Nordstrom stylist and tell them you specifically need help finding jeans. Try on everything until you find what works. Try designer brands. If you like cuts or washes that aren't available at retail, try thrift shops. If you find designer ones that work, and you don't want to pay designer prices, look at places like Marshalls, TJ Maxx, Rack, or even secondhand shops like ebay, ThredUP, or poshmark.
The perfect jean is out there, you just have to hunt for them.
