Some people don't think make up is beautiful. Don't beg. When you move out, feel free to get makeup as much as you want. NOTE: makeup costs money and only makes you pretty my advice is to put the whole thing behind you.
by telling her to buy it
Tell her that you want to get one for when you need it
Rue21 or goodwill
Tell her you want to wear makeup and you promise not to look "slutty" when you do.
because she probably thinks that it's inappropriate
You could try asking her to let you wear the bare minimum- for example, some tinted moisturiser, concealer, powder and mascara. Even let her help you buy the products.
Three products: powder, lip gloss and mascara. See if you can convince your mom to let you wear tinted lip gloss, otherwise clear will do. Since you're in sixth grade that's all I'd use on you even if your mom was okay with you wearing makeup--a lot of schools freak out if sixth graders wear makeup.
where? Where? What jurisdiction?
i would say be really responsible aka don't argue, do all your chores, everything extra she tells you, without complaining. once she sees your mature and responsible, she MIGHT let you wear it. it varies with each mom.
Yell at her.
You could play it up and say how makeup gives you more self-confidence? Or promis to only use neutral colours. Or you could promise to onlyy use lipgloss and mascara and then eventually ask to use other things?
because school is importanat. and your mom only wants the best for you and to get an education
