Fit Tips

• Every style may fit a little differently, so be sure to check the product description for item-specific fit recommendations.

• Ari’s measurements can be found in the Model Measurements tab for additional sizing reference.

• If you’re between sizes, we generally recommend sizing up for a more comfortable fit.

To help keep your By Ari Boutique piece looking its best, we recommend:

• Machine wash cold on a delicate cycle
• Wash with like colors
• Do not bleach
• Tumble dry low on a delicate cycle
• Low iron if needed
• Dry clean optional

Proper care helps preserve the quality, color, and fit of your favorite pieces so you can wear them again and again.
