I won't hammer home the point that those jackets are too big. However, since you've posted a number of questions about personal fit, I'd like to offer a few pointers. For starters, get to know clothing. Not just labels/brands, but some of the construction methods, materials, etc. If you're interested in dressing better on a daily basis (CM or SWD), start keeping up with some of the picture-heavy threads on StyleForum. There are also a number of great (and even more that are terrible) menswear blogs/tumblrs available to glance at regularly. When you see things that you like, start breaking it down. Do you like the how the colours play together? Textures? Is it the fit of the garments themselves?
By putting in some of your energy into research, you'll save yourself the headache at the stores. Besides, taking a look at other styles is a hobby for me. I wouldn't wear a total RO, YY, EG look myself, but I love when others do it really well. I also wouldn't don a Balenciaga gown, but I definitely prefer reading about Cristóbal Balenciaga rather than my regular work.
