I buy from them all of the time for my teenage daughter. We do not live in the UK and her school dress code is fairly smart so the casual dresses work really well. The Too Much Fun dress is fabulous. Very thick cotton and good quality and not too short!
She has had one dress that I thought was a bit cheap looking for prom, but she loved it.
I have also bought a couple of the sweaters for myself. As long as you read the details and avoid the stuff that is 100% polyester I really recommend them.
Shipping is really fast and customer service is excellent.
