Tanning issues

Hello ladies, I’m a ginger with very pale skin but I just recently noticed I’ve been getting a tan on my shoulders, face and arms but no where else, I really wanna start tanning in my backyard cause my pale skin is my biggest insecurity and I’d like to fix it before my 16th birthday party in 11 days cause I’m wearing a cute white pantsuit and I think if I tanned it would really complete the look 😂 but I’m not really sure how cause I’ve never actually tanned before, do I apply sun screen or not and if so how much sun screen, I also burn easily and it’s a pain cause I’m allergic to aloe so can’t use it, that being said I also need a certain type of sunscreen. Below is a picture of my porcelain skin tone 🤦🏼‍♀️
