Welcome to TFF!
To be quite frank, it's usually not a problem. I must admit that, as well as when people choose their outfit, one should consider the proportions, in my honest opinion. Being chubby isn't something that needs to be hidden or ashamed of, after all. Go for what you feel like and see what works best for your body. In my example, I'm quite underweight and shouldn't wear things that make me look even thinner. I used to wear a dark purple pinstripe blazer. People actually asked me, if I was sick, as it made me look even more skinny than I'd do in other clothes.
All in all, you're good, as long as you're happy with yourself (and those around you).
Have a good time here on TFF.
