Many reviews focus on return and refund problems, including refunds issued as store credit and long wait times. Several customers also highlight fast, effective live-chat support, often naming agents. Product opinions split between praise for fit and stitching and complaints about creased, wrong, or stained items. Multiple customers mention delivery and tracking mistakes.
Examples from available reviews (Feb 2016 – Mar 2026).
Refund defaults to gift card unless you opt for original payment.
“you now have to ‘opt’ to have any refund credited to your original payment card otherwise you get a ‘gift card’”
WhatsApp chat gave an almost instant, reassuring response and solved query.
“Used the WhatsApp chat service and had a virtually instant response...”
Order arrived quickly; quality and fit were excellent despite simple packaging.
“the quality was as described and the fit and feel is fabulous!”
Received wrong, stained jumpsuit that appeared previously worn.
“The item arrived dirty, stain under armpits, as well as next to the zipper.”
Negative reviews mostly center on returns and refunds. Several customers say refunds came as vouchers instead of back to the original payment method, took longer than legal timeframes, or never arrived after orders were lost. Some also report unexpected return fees and unexplained extra charges.
Unexpected charges lead many customers to question the value. Reviewers mention fees described as swap protection, delivery protection, or higher return costs that they did not anticipate. Some praise the clothing quality, but that does not outweigh repeated complaints about how refunds are handled.
Several reviews point to website and fulfilment friction. Customers mention sizing differences, unclear return labels, and packaging issues like strong smells or items arriving creased. These issues appear less often than refund and service complaints, but they still come up.
Product feedback falls into two distinct camps. Many reviewers praise the fit, stitching, and finish, describing dresses and coats as well made. Others say they received the wrong item, or items that were stained or previously worn, and some describe a drop in quality since the ownership change.
Live chat and WhatsApp get steady praise for quick, helpful support, with agents often mentioned by name. Email and phone draw frequent complaints about no replies or bot-only responses. Some customers also report incorrect tracking and late delivery updates.
Overall views split sharply between standout one-to-one support and broader service breakdowns. Some shoppers describe excellent in-chat fixes and satisfying purchases, while more reports focus on unresolved refunds and weak post-sale support. That contrast heavily shapes impressions.

I recently shopped at Karen Millen and had an excellent experience. The store had a stunning range of women's clothing for all occasions, from workwear to weekend wear to special events.
The clothes were not only stylish but also of high quality and made me feel confident in my appearance. I was impressed with the tailoring on their dresses, which perfectly cinched in my waist and draped beautifully over my curves.
In addition, the staff were incredibly helpful and knowledgeable about their products. They provided me with personalized styling advice that suited both my body type as well as budget.
Overall, I would highly recommend Karen Millen to anyone looking for fashionable yet elegant women’s clothing that exudes confidence and poise.
