What seamless underwear to wear with Align leggings? - eviltoast

I just got a pair of purple align leggings. LOVE them but my underwear is totally visible. Never had this issue with my black and gray align leggings.

What seamless bikini underwear do you wear with Aligns? I hate thongs. I’m a nearly 40-year old mama and prefer to wear underwear with lots of coverage. Is Knix a good option? (I’m in Canada).
