One thing to consider for a true perfect fit is getting alterations. If you find a pair that fit your ASSets but don't fit your waist, get them taken in. Or if everything looks good but they bunch up at your feet--have them hemmed. The general rule is to buy the size that fits the widest part of your body. Be sure to sit down and move around to see how they shift when you shift. Seems simple enough right? Another idea is to try multiple designers and find a designer that fits your body type the best--some labels are made for flatter figures (Chip & Pepper, Seven) where others are cut for the curvy chic (Gap curvy, Citizens, Joe's)...
Now while we are on the topic of jeans, another thing I am finding myself wearing less and less (like the smoky eye I mentioned here) are low rise cuts and skinny jeans! I am drawn to the refreshing high waisted, wide leg trouser as of lately (among others) and I suspect these will be on the rise this spring. Thought I'd share some of my favorites:
TheGap.com 1969 Curvy Jeans $69.50
CitizensofHumanity.com Citizens of Humanity Lennox Tapered Loose Fit
Happy hunting (and goodbye muffin top)!
