I'm 5'5'' tall and weigh 130 pounds. I need very slim, tailored fitting trousers in waist size 28. I live in Las Vegas so it's really hot most of the year so I dont need heavy weight pants for warmth. However, I do need them to look dressy. Does linen/cotton look too casual? Which brands make size 28 and very slim? Do Nordstrom brands include free in-house tailoring? That would be nice. What about Saks? Neiman Marcus? No more than $150 per pants. When are the big sales for these stores? I need to stock up.
