Embrace Monochrome
Dressing in black, navy, camel or grey elevates every discount pick.
Layer with Strategy
A sweater over a shirt under a coat adds depth—even to sale buys.
Mix Textures
Wool coats, silk tops, leather accessories: rich visual appeal at low cost.
Invest in Accessories
A leather belt or smart bag from AllSaints or John Lewis pulls an outfit together.
Hold Off Trend Splurges
Limit bold, fleeting trends. Instead choose 1–2 low-cost pieces—like a summer floral top.
