SizeAssistant is a free Chrome extension developed by AlixBlog in the category of Browsers, specifically Add-ons & Tools. This extension aims to make online clothes shopping easier by recommending the best size for users when browsing clothes on Shein.

With SizeAssistant, users simply need to add their measurements once, and the extension will take care of the rest. It uses this information to find the most suitable size for each garment. When the size has been determined, users can click on the purple check mark to open a convenient size chart that visually showcases how their unique measurements align with each item of clothing.

It is important to note that SizeAssistant is currently designed exclusively for women's clothing on Shein. Additionally, there may be certain items for which sizing recommendations are not available if Shein hasn't provided complete sizing information. Therefore, it is recommended that users double-check the size chart before making a purchase.
