I need a makeover for summer!?

i really need a new look for summer! i want longer hair but it doesnt grow:( i was thinking of getting extentions but i didnt know if you would be able to see them in my hair because my hair is pretty thin tbh+ i need some new clothes, does anybody know like the latest fashion items? also i always where the same makeup and im getting bored of it now, i wear dream matte mouse and the liquid on of that, with some maybeline powder over the top, with some miss sporty blusher(full on red) and i put loads of mascara on because i want my eyelashes fuller and longer but they always go clumpy and i hate it, then some barry m lip paint usually pale pink or peach with a gloss over the top, i wanna try something different and i want some new clothes, if anyone has and advice or ideas i would be greatful many thanks!:DDDD
