If you want to wear a mini dress then you absolutely should go for it, as long as you have a good sense of what works and what doesn't work on your own body. Unless you have a huge amount of confidence and a picture-perfect figure it's best to stay away from the modern/strange looks and instead opt for the modern/classic looks. Choose a mini dress that's about mid-thigh in length or slightly shorter, but never so short that your bum hangs out the back or you can't sit comfortably and modestly. If you are looking for a splash of colour consider a mini dress with a fun and trendy print to it, like polka dots, distinctive floral, or an all over bold colour like red, royal blue, emerald green, or the like.
Most of us simply want a mini dress that's comfortable, stylish, and practical for everyday living, so don't be afraid to shop around for more casual mini dress styles.
