Question to ladies about thigh highs

[asambuk]

Hello everybody. My girlfriend likes thigh highs, but she does not like silicone strips at all. She also does not want to attach them to any waistband.
I heard some Japanese stores offer such thigh highs: with no-silicone band, not requiring any waist attachment, holding on leg on their own. Is this true? Can you advise something on shops / brands please.

Many thanks and have a good day!
