Wide shoulders means you can play off a sleeveless top fairly well. I went with a sheer cowl, one with a good drape that will help people not look at the problem area tummy that a lot of Y's have.
It can be hard for a woman with no hips to pull off a pencil skirt, but if it's got wrap detailing sometimes we can get away with it. Especially this one with it's wide leather waist to add a bit more curve to our bodies. Knee high boots with a skirt that comes to just below the knee's can look vary chic when played off right. Keep to a simple boot if you are going to have fun skirt.
If you're going to have long dangling earrings, don't bother with a necklace, you just look busy. It's the same with large cuffs and rings, you don't want to overdo your accessories.
