"Don’t rush the process," agrees editorial coordinator Ali Carey. "Try on as many cuts, sizes and washes as you want before making your final choice. Remember vintage denim often has less or no elastane compared to a new pair of jeans, so keep in mind that they will wear differently and age well, but - at the risk of getting 'saggy bottom' - buy them as firm fitting as you can. Also, don't be afraid of a men's jean- sometimes with a little bit of altering they can work in your favour."
"My advice is if you find a wash or cut that you like, buy them even if they're a little big," adds market editor Tara Morris. "I've practically had all my Levi's altered to fit me right since the cuts seem to change quite a bit."
Would they buy vintage denim online? "If all the measurements were listed," says Morris. "And if there's an easy returns policy," says Russell.
But if you're not quite ready to dive in, consider reconstructed denim - brands like Re/Done take vinatge jeans apart at the seams and re-tailor for a more modern fit - or seek out Levi's throwback styles or washed-out colours like the below.
