My favorite short ! So flattering I can't cope

I’ve been a SEFI girl since their launch and let me just say… they never miss! Every collection has me adding to cart instantly – the designs are always so chic, flattering, and wearable. Whether I’m dressing up or just running errands, SEFI pieces make me feel like that girl.
The fabric? DREAMY. So soft, so luxe, and the quality is next level – everything washes well and still looks brand new months (even years!) later. You can really tell they put love into every detail.
I’m always getting compliments when I wear SEFI, and I honestly can’t recommend them enough. Stylish, comfy, and confidence-boosting – what more could you want? 💗
Forever a loyal fan!

It is extremely difficult to find sports clothes that are not only beautiful but have a superb quality, for the sefi brand this is the case, I love their clothes and with them the WeGLOW App so a huge thank you to Stefanie Williams 🤍

Always delivered super quickly. The quality of the products are unmatched and everything is just so stunning. I've been buying from Sefi for years now and I'm never disappointed! Love the different materials and designs, always looks so flattering on.

Love the fitting!

I love the quality of the activewear sold. I have been wearing Sefi for a few years now. Love the attention to detail and the comfort of quality. I would say definitely worth each penny. All the designs are very well thought out and are so comfortable. They definitely add to the feeling of looking cute whilst being active.

You really can’t beat the quality of their active clothing! All my Sefi clothes still look like new. Absolutely love this brand 🫶🏼🫶🏼🫶🏼

Always super high quality and the fit of the clothes is perfect! Very happy with all the products I’ve purchased.

Ordered early July. Promised delivery in 5–9 business days. The package showed up 2 weeks late — with zero updates, no apology, nothing. I had to chase them down, and even then, the replies were vague, lazy, and clearly not even reading my messages.

The customer service is a joke. They didn’t care it was late, didn’t acknowledge it ruined a gift, and never took responsibility for anything. Just auto-replies and empty gestures.

Then the sizing? Absolutely off. Ridiculously small. Nothing like the size guide.

And returning the items? Another scam:
➡️ £20 return cost — for a £37 item
➡️ No prepaid label
➡️ Return is fully at your expense
➡️ No refund of shipping costs

Basically, they make returns as painful and expensive as possible so you give up.

This brand looks polished on Instagram but behind the scenes it’s all smoke and mirrors.

❌ Delivery promises: fake

❌ Customer support: non-existent

❌ Sizing: inaccurate

❌ Returns: overpriced and discouraging

❌ Accountability: zero

Save yourself the trouble. Plenty of other brands out there actually respect their customers.
