Buying from UK Disturbia to the USA

Hello all. Somewhat random question here. I’m an American citizen who’s been living abroad for 3 years. I’m visiting my family next month and really want to purchase some clothes from Disturbia.

I have no experience with the whole tariff issues so I’m going into this quite blind. Have any Americans here recently ordered from Disturbia? Did you experience tariff fees/what was the process like?
