Would pantyhose under riding breeches help?

i am fifteen and I've been riding for about 10 years now. i love riding and everything but i just hate panty lines! i've tried thongs (too uncomfortable), g-strings (same), and i wont try commando (just gross IMO). But it's really embarring to be showing and looking down and seeing a flash of green or pink or black and knowing everyone in the audience knows what color and type of undies you got on...i mean im usually wearing bikini cuts and i've heard that lace around the leg openings can help break up lines. But I'm considering trying pantyhose or tights under my riding breeches, might this work?
