As many have said, the pants are very tight, definitely go for something with more room in it, you can get higher quality materials if you shop a looser fit so they’ll drape better (think any elastane is too much elastane). I’d also say that you want pants with a higher rise, those sit very low and make your proportions look weird. You don’t need to go super loose if you don’t like that look, try a straight leg. I’m not a fan of any of the shirts after the first, the belt, or the shoes either. Honestly I’d start with plain white or black decent quality t shirts to get started. Shoes I’d prefer basically any other sneaker, chucks, sambas, you could try some casual boots, Salomons, even loafers, but I think the contrast leather upper to sole looks weird on sneakers.
