Much too broad of a query.
If you are looking for tops and trousers, the beauty of on line shopping is that you can narrow down your query to specify what you are looking for. Long sleeve tops? Blue or green? Linen or cotton? Most sites now have filters to narrow down your selection.
Instead of endlessly browsing 800 tops, narrow down to your size, preferred colour, sleeve length etc. For instance Boden has 520 women's tops. Narrow that down to long sleeve, blouse, blue, and there are 19 to choose from.
This way you can find something that will work with the wardrobe you already have.
