How to choose the right size? I sew in four conventional sizes. An approximate size table will facilitate selection. A tailor's measuring tape will help you take accurate measurements. We each have a different ratio of chest to breast size and muscle volume. The types of back systems have small specifics and it is necessary to take into account the strength and elasticity of the fabric. If you have a favorite and hesitate if you will fit the rate, send a photo - I will give you an advise.

Is it possible to try the bras somewhere?

Definitely in Frýdek-Místek, where the Kefin workshop is based. You can usually find me here Monday to Friday from 8 AM to 3 PM. It's best to call or send a text message in advance. You can always find my products at the yoga studio Jóga pod věží in Frýdek. In 2025, I will also be showcasing my collection at the reception of the PodCísař campsite in Ostrov u Tisé. Every year, we participate in the International Mountaineering Festival in Teplice nad Metují. Occasionally, we also attend Mint Market or other events, and I always announce these in advance through social media stories. Throughout the year, I travel to various natural locations—mainly rock and mountain areas. I always keep a selection of bras in different sizes and designs in my car, so there's a chance we can arrange a strategic meet-up somewhere.

Do you offer a version for nursing women?

Yes and no. When I was pregnant and nursing, I had many friends in the same situation, so I explored this topic in depth. We tested different fastening options at the top of the shoulder, among others. In the end, we all agreed that none of them were necessary. The fastenings were often uncomfortable, scratched the skin, and were difficult to find when trying to reattach the strap after nursing. In practice, whenever our babies were crying, we all ended up simply pulling the bra down over the neckline or up from the bottom under the band—quick and hassle-free. So, YES—Kefin bras are also suitable for nursing, and there’s no need for any special cut or modification. Plus, if you lose weight after finishing breastfeeding, you can have your bra resized. Please consult me before sending it back—I’ll need a few photos from you!

I have an atypical body shape – is a Kefin bra right for me?

YES! Many of my customers have atypical body shapes—whether it’s a wide chest with small breasts, a petite frame with a fuller bust, or other unique physical characteristics. Kefin bras are made for EVERYONE! I have extensive experience in pattern construction, and the materials I use are incredibly adaptable. In your case, a custom-made bra would be the best choice. When ordering, leave a comment describing any concerns or issues you've had with bras in the past. I will reach out to you, and together, we’ll fine-tune every detail to ensure the perfect fit that meets all your expectations.

Wearing sports bras gives me neck pain – do you have a solution?

YES! I personally struggle with the same issue. Halter-neck swimwear is a no-go for me, and I often couldn’t wear crisscross back designs offered by mainstream brands. I firmly believe that standard sports bra patterns are not designed for the average Czech woman, which is why they often don’t fit well. That’s exactly why I spent years thoroughly testing all nine back variations (including swim tops) on myself and my friends. Kefin bras truly fit well! If you're unsure about your choice, don’t hesitate to send me a message—we’ll find the perfect solution together.

I have skin issues and can’t wear synthetic materials—do you have a solution?

YES! Many customers with similar concerns reach out to me. The inner lining—the part that touches your skin—is made from merino wool or bamboo knit fabric. For the back design, we choose a simple style with flat elastic bands, all of which are enclosed in bamboo fabric tunnels. The only synthetic material that touches your skin is the Kefin logo, which is necessary to cover the main seam and ensure the bra looks neat and finished. If you have this issue and would like a bra designed for sensitive skin, place a custom order and describe your needs in the comment section. I’ll reach out to you, and together we’ll fine-tune every detail to make sure your bra fits perfectly and meets all your expectations.

How ofter are the collections renewed? Every month there are about 30 new pieces produced in my workshop. I update the shop continuously. It is not in my power to always put all new bras into Eshop. Where and how I will present them myself today I do not know yet. Wait - watch me continuously - wish and get.

I bought a bra and it doesn't fit, what can i do? YES, I do replace stretched-out elastics on Kefin bras. You can find the conditions on the BLOG in the article Bra Repair.
