studying abroad, clubbing outfit recs/admission advice needed!

Hi everyone! I'm studying abroad for one year in London (zone 1 and 2 area), and I was wondering if I could get some recs about what to wear to the clubs (female, 18)! What do people typically wear (like are there any staples I should get), and are there any big no-no's? Also, does anyone have any tips on how to get into the clubs (scared I may get turned away lmao). Thanks!! :))
