Hmmm. I think my top 3 would be:

1. T-shirt
2. Baseball cap. Maybe a sap one. It’d keep it from blowing away on a windy day. And PLEASE make them large. The majority of every baseball cap I try doesn’t fit. I only have 1 baseball cap that fits. Quality ones would be nice. I hate crappy quality ones with cheap adjustment straps and they don’t look as nice. And no mesh “trucker style” please.
3. Can’t decide, probably either a zip up hoodie, or patches
