Can you get STD this way? Please read

Today I was at the store and I liked this skirt but there was only one and one lady before me tried it out and then handed it to me because she didn't want to buy it and I wanted to try it too. So, i tried it out right after her but now I'm afraid to contract something this way? I also tried out 2 pairs of jeans before the skirt.

Btw I was wearing underwear of course, and nylons. I was also wearing a panty liner but I threw it away when i got home because I didn't need it anymore and forgot to change my underwear and changed them as soon as I remember like 2h afterwards.

I'm really scared. I would love any advice.
