A matching teacup, saucer and teapot.
I saw these at Whittard who seem to have the best variety although are more expensive than others I've seen in TK Maxx, Dunelm Mill but are more plain. However, you do not need to compromise between design and price.
The Solution: Whittard of Chelsea outlet stores where they're usually half the price.
There are also stores in York and Swindon.
I shall be picking up my favourite if/when they arrive in store.
