Ah, the old concert footwear conundrum.
I have seen a few girls bravely attempt to wear heels at a show, and I have seen many of them knocked down or tripped up or limping around later.
Luckily, girls usually have a bit of nightclub leeway, so unless the places you plan to party at are super-fancy, you can get away with a pair of bright skinny jeans and a non-casual black top (think lacy details or low back), an outfit that should also suit you fine at the show.
Check if the concert venue has a coat check–if they do, stash your heels there and opt for flats if it’s a low-key show and closed toe boots if it might get rowdy.
Intact toes are well worth toting around an extra pair of shoes all night.
Get the look!
