Women may be used to hearing that high heels can be a source of back problems, but did you know that other articles of clothing may be doing your body more harm than good? If you’re dealing with back aches, examine your weekly wardrobe to see if you’re wearing any of these items frequently.

1. Skinny jeans. This popular fashion trend may be cute and comfy, but new research says that tight jeans may restrict movement in the hips and knees, interrupting proper body posture.

2. Backless shoes. Wearing sandals without a back can lead to foot problems as you’ll walk differently than you normally would.

3. Oversized shoulder bags. Men, women and children who carry heavy purses or backpacks every day can develop back problems. A good rule of thumb is to make sure your bag is no more than 10% of your body weight and not carried to one side.
