You can check the authenticity of Aidai bras by checking the trademarks and labels, observing the details, verifying the tags, comparing the feel, and referring to professional certification agencies.

1. Check the trademark and label: Check whether the brand trademark on the bra label is clear and standardized, and whether the brand name is spelled correctly.

2. Observe the details: Check whether the hooks, bandages, shoulder straps and other details are firm and smooth, and whether there is any pilling, fluffing, etc.

3. Verify the hangtag: Check whether the hangtag is clear and complete, whether the printing quality is high-definition, and whether it is consistent with the product information.

4. Compare the feel: the feel of authentic and fake bras is different. The authentic bra is soft to the touch and made of fine materials.

5. Refer to professional certification agencies: If possible, you can refer to the identification results of professional certification agencies, such as the National Textile Product Quality Supervision and Inspection Center.

It is recommended to purchase from regular shopping malls, official websites or legal dealers to avoid buying fakes. If you think there are quality problems with your bra, you can make a complaint to the store or headquarters.
