Wiggle are actually OK with returning unused stuff for colour or size problems, like most mail order clothing companies:

What do I do if an item doesn't fit or I don't like the colour?
For UK and international customers please return it to us within 365 days. Just complete our returns procedure before sending us back the goods. Returned goods must be unused, and supplied with their original packaging.
