What do you think a Welsh woman should look like? 
Like this?! 😆
Like the majority of countries in the world, in Wales there are some people with a mix of ethnicities in their blood/people of various ethnicities, (and many of them were born there!)
I mean, that would be like seeing Stormzy on TV who was born and raised in Croydon, and say ' hmm, he doesn't look English!'
Look at Catherine Zeta Jones for example. Same dark hair, darker skin, and brown eyes, yet she's WELSH. What about Shirley Bassey.. WELSH. 
Not everyone who lives in Wales is going to be light skinned and blue eyed. There's lots of different ethnicities and religions in Wales... Muslim and Hindu and Sikh and Buddhist communities live there... amongst a few others. Cardiff houses around 80% of the Muslims that live in Wales.
Have you never heard of Tiger Bay?
