70's Glam!
To achieve the vintage vibe that is the 1970's, you will need confidence to pull of the look before even looking at what to wear! The '70's brought a style of voluminous figures, meaning flared trousers, billowing sleeves, backcombed hair, etc.
The outfit (most likely not to be worn together,but an idea of styles):


Shirt, £32.00, Topshop.
Brogues, £59.99, Hush Puppies @ Schuh
