Bonjour j'ai un devoir en anglais ou je dois imaginer un dialogue entre moi et une caissière P.S pas de traduction internet

je suis bilingue, tu peux compter sur moi ^^ pas de traduction internet

shop assistant- welcome to "fancy shopping" [change de nom si tu veux]. Are you looking for some particular clothes?
me- Hi! I am looking for a party outfit. Do you have, by any chance, something flashy and exciting?
shop assistant- We have exactly what you are looking for! Here it is. A flashy blue short skirt and a very exciting crop top which will make you look brilliant!
me- i do like that top, but... I don't think this skirt is what I am looking for. 
Shop assistant- Oh. What a shame... What about... These shorts? They would fit you marvelously and they would also look great with the crop top!
me- Yes... I do like those very much...only that i'll freeze to death in winter!
shop assistant- just put some leggings underneath, and it'll be great and warm.
me- yes, thank you very much
shop assistant- it'll be £25 
me- Here's £28. keep the change :D
BONNE CHANCE :D
