Sort of personal question for women that ride English?

I'm a western rider, but next week my cousin who owns an English barn is going to teach the basics of jumping on one of her horses. She told me she'd prefer I didn't come in my usual attire - jeans, a tank and my boots, and that I wear breeches and borrow a pair of her boots. My question, which is kind of silly but anyways, do breeches ever...stick to you down there? like give you a camel toe or anything? I've never noticed but never looked hard enough to pay attention. Anyways, thanks for the answers.
