Nordstrom Rack has everything. I’ll get their shoes because they have a wide variety for a good price. From Aldo to Cole Haan. I’ll get my jeans and polos from Old Navy or Gap online, only because of their deals (50% off on ‘premium’ jeans) and I like my shirts in Tall sizes. But jackets, bags, shoes at Nordstrom Rack.
Figure out color scheme and garment style first, then just go anywhere you want during back-to-school time when they're offloading last year's winter and spring stuff and marking everything down. When I was at U of H I used to take the crosstown #68 to right outside Meyerland Plaza and shop at T&C Men's Mart which then became K&G Superstore. Another strategy would be to spend what you want on whatever brand you like, then dry clean everything and never gain weight. Cheap and ubiquitous dry cleaning is one of the better perks of being in a major city like Houston.
My bespoke tailor is also at Sharpstown. Nothing but the best and most elegant malls for high quality tailors like ours.
