Combing textures is a great way to achieve a rich look. Try this formula: tweed blazer + ribbed tank + coated jeans + leather belt / shoe. My jeans are on mega sale (70% off!) and available in petite, and short and long inseams.
Wearing:
Blazer: size small (if in between size down)
Tank: size small (if in between size down)
Jeans: size 6 (TTS)
