Tldr: is this too small, should i return it and order again in the next size up.

So the other day i (25m in the closet, pre anything) saw super cute V-String Panty from pink, and decided that given the price, and that i don't have any panties, to order it. Just got them in the mail today, and after trying them on (after my parents left the house) I'm worried they might one size to small. When i was ordering, I had gotten my moms help to measure my hips and waist since the last measurements i had written down were 2 years old. we measured my waist at 35in and hips 39in. None of the size options fit both my hip and waist measurements. Since I'm not out to my parents who i still live with i had to dance around what i was ordering just saying under wear, and asking if none of the size options fit both which should i go with. she said just get the size i normally wear (again i just said i was ordering underwear) which is large (yes ik mens and women's size are different) as i said earlier im little worried i might have gone one size too small, and since cant just ask my mom, i was hoping to get some second opinions from you lovely people.
