Buying jeans is what made me realize I had to try stuff on in stores before I bought them. I have a pile of ill-fitting jeans in my closet which I won't wear!
When I was younger, I used to fight my girfriend over Levi's 517 jeans we could only find in thrift stores, that was the jean we BOTH looked best in.
Now, however, it's Calvin Klein's "Calvin Bootcut" jean, which I have in sizes from 6 to 12 because I balloon up and down in weight, and yes, I hate you size 4 and 2 and 0 girls, but I'm over it.
Anyway, the thing about jeans is you have to try a lot and when you find the ones that work, you'll just know! The thing is, you won't REALLY know in the store, you can only know if they fit in the store. You have to live with them a bit before you know that THESE are THE JEANS for you. I was lucky, I can buy my favorites online from
Macys.com and not have to hunt for the right waist and inseam! Lucky for me, too, because they're really flimsy, they tear where your butt meets your thigh in like, a dozen washings!
Or does that say something about my butt???

Best luck on your bluejean adventures, m'luvs!
