Underwear question

Is it safe to wear the same panties for more than a day? I’m 14 and only have like 10-15 pairs of underwear. I try to stretch my laundry out but I’m not always successful. Everywhere in my state is closed, but I’m nervous to order underwear online. I like to try it on in person. Plus I think my mom is a little tight on money. I wanna order from VS or PINK but I think she’ll make me get the prepackaged panties from Walmart or target. What should I do? I know girls will make fun of me for having Walmart panties instead of PINK
