If you are an Hourglass Shape your top and bottom are proportionate while your waist is small.
I have linked to posts that already have information on the topics. Otherwise, I have given you a bit to go on.
If you’re going to wear a shirt with any kind of embellishment or ruffles or anything then you need to make sure that you’re balancing that out somehow on the bottom.
You do need to make sure your waist is pulled in. So wear a belt or tuck in your blouse. Also, if you don’t tuck in your blouse, make sure that it’s not landing on your hips and making them appear wider.
Skirts and Mini Skirts:
Skirts with a higher waist are great for your shape. You can go for any fit of skirt.
