Most things you can machine wash, or anti-bac. There’s very little we haven’t got secondhand. We’re really trying to minimise our impact on the environment, there is just so much stuff already out there - it also helps financially too!!
Could always wash but also if you want that further peace of mind try find one with tags/unused - just filter it on vinted :)
I'd say pop it in a wash and it should be fine. Wash it twice if you are nervous x
Most of them you can stick in the washing machine so should be ok. Maybe ask the seller for a picture of the care instructions? Before purchasing. I’ve got a second hand one and it was all machine washable.
