Mam copy's everything!

Ok so I'm new on here this is my first post as I only thort to seek help through a problem forum.here's the thing so I'm 23 and my mam is 42 next week and looks good for her age (although slightly overweight horrible to say I know but its true) but for the past couple on months she's been copying everthing and trying to out do me ie:we go out for a night on the town every so couple of weeks, and 1 of them girls who likes a lot of tan big fake eye lashes and hair extensions so on..I like that I transform myself from my day to day boring mam look to looking quite nice (although its fake i know) anyway going on abit now sorry, anyhow she has started to say things like I'm gunna be browner than you tonight and I've got the biggest eyelashes blah blah so on and so on.so yesterday I told her I was getting my hair stripped and dyed pink next week..so this morning I get a txt from her saying she's booked into the hair dressers for tomorrow and and there's a pic attached its only the exact same as what I've booked in to get done! I'm fuming with her sheen had the cheek to ask me to pick my sister up from school because she wouldn't be back from the hair dressers in time! I mean come on this has gotta be worse than a little sister copying everything from you. She had even ordered a pink pair of stilettos with barbie wrote down them *cringe* she caneven wear heels at all,she's always trying to out-do me I should be flattered but its annoying now. Any ideas how to get her to stop I've tried telling her but she just thinks she's a cool mam she even asked me a few weeks ago which trainers made her look more chavvy? (She was already in a tracksuit*cringe again* blonde hair scraped up in a messy bun) she was going to do the school run for gods sake! Is this a midlife crisis?

It's horrible to say? But you should downgrade her and Mae herself feel bad to what she's wearing and stuff, that way she will be like, what's wrong with it? & go to change to something you recommend her.
