Madrid and Barcelona are famous for their night life.
Madrid natives are literally referred to as “gatos,” or for those not savvy: cats.
This has more to do with a battle hundreds of years ago, but is just as applicable in the vein of thought that cats stay up all night, on the prowl.
Madrileñas party from sundown to sunup and I am not even a little bit exaggerating.
Granted, the “party” probably starts with an 11pm dinner with parents, but just the same, late nights and early mornings are a way of life in the Spanish capital.

So when you go out (no if, when) be mindful that this is a city built upon seven hills, as the story goes, and I don’t know about you, but walking in hills in stilettos is a no-go.
Get some cute sneakers. Locals rock this look a lot: hence the glitter Keds in the style guide!
Black, white, and grey are still going to be the most common colors you see girls wearing out, even to night clubs, but there is a bit more color in club wear, it seems. Red is always promising.
And just like in the daytime, if you are going to carry a purse, it should be a cross-body bag, to deter purse thieves. The smaller the better, so it doesn’t get in you way as you dance, and its harder for a pick=pocket to get in to!!
All the chic as hell local girls will be in crop tops and/or leather leggings. If not the night you go out, its what they were wearing the last time they went out. Trust me, its worth the wardrobe adventure.
REALLY if there’s anything you’ve wanted to experiment with stylistically, clubbing in Madrid is the time to do it! Experiment a little. Hence, the feathers, shirt with the weird sleeves, and the statement necklace in the style guide above!!!!
Spanish girls are cool. Embody coolness and they’ll be slightly less likely to sneer at you in line for the club.
Just barely less likely, but still.
