When choosing a workout attire look for something that matches the kind of workout you are doing, for example if you are lifting weights and track suit wouldn’t be recommended. However, one general rule is not to choose clothes that are too tight because they can reduce your range of motion, also do not wear too much clothes as you can really get hot and uncomfortable. Wearing a jacket is only so you can warm up properly but after that consider taking it off. Also choose your brands wisely make sure you choose brands that are gear towards making sports clothes like Adidas for example. (Like when you buy a speaker system for your home you should go for bose l1 musicians friend for better sound appreciation.)
