Hello Mummies

My lil one has a pirates and princesses party this weekend(all this theme party wahala sef she hasa football one next weekend i dont know whey we cant just wear our own clothes and chop rice). I have looked in most of the high street stores and cant seeem to find something princessy(is that even english ).She has ball gowns obviously but i just think they dont tie into the fun dress up effect.So can anyone suggest where i can get a princess outfit for a 2 yr old(at an affordable rate as well will not spend £80 on a costume).
Or should i just blag it and wear the ball gown for the girl sef and look for one shiny tiara type thing to put on her head?
Her father has even suggested we dont play into gender stereotypes and dress her up as a pirate
what do you think?suggestions welcome.

@op
have you tried tk max?
hammersmith and ealing branches are better stocked with children's costumes
Asda to sometimes does this but you have to check
