The whole point here is how you feel about your waist: you are saying that it helps to accentuate your figure and make your body looks fuller, but it also makes your shoulders look wide. Personally I would like that effect, but what about you?
Forget about what people say, as a small percentage of people are always ready to criticise, whatever you do. Be respectful and kind and wear whatever you fancy.
I guess the best is being proud of your body and not hiding it. That doesn’t mean wearing super tights clothes, since that would require being very motivated about showing off.
The recent Fashion Weeks proposed a lot of figure-hugging outfits. Go for loose fabrics gently showing your shape, avoid bandage dresses and built in belts. Here some example of gentle styles.
