Since there's no Pull&Bear stores around here I'll only be able to speak about the store's online purchases service.
I've always, without a fail received my orders within 2-3 days, eventho I live in a rural area.
The clothes are always like such good quality it's crazy, they are a bit pricey but that's definitely excusable by the 10/10 material and designs.
Never been scammed or had anything happen to my purchases, and I've ordered everything from shirts to sweaters all the way over to accessories so yea definitely trustworthy and I'd recommend it.
Kinda sad there's no review/rating option on the website and app so I was sceptical at first but I hope I could help anyone who was questioning Pull&Bear's legitness.
