Vaginal Odor

Is it normal to have your vaginal odor go through your jeans/shorts/leggings? I can always smell myself and I’m pretty sure if someone is near me when I open my legs can smell. I’m so insecure about this. The smell is not bad but I just don’t understand why I can smell through my underwear and pants. It’s really concerning as I don’t know if this is normal. If it’s not what can I do? I will say since i’ve gained a lot of weight I sweat a lot more and I find my private area sweating more and this is probably the only reason I can find.. or maybe my diet. Ugh, i need help. I’m so insecure and try to keep my legs closed most of the time now.
