What to wear??

so my and my 2 older brothers are getting our pictures done for our mom for mothers day. and idk what to wear I told my brothers to wear black t shirts and jeans. my moms prefers pictures that's are casual and look like her kids everyday not all dressed up. but with my brothers matching I have to be the contrast and idk what to wear to make the pictures look best or something my brother should wear something else. PS I have big red hair right now too. idea anyone?
