Sielei Bras

Which style to choose

Alongside elastane and cotton, the compositions often include modal: a cellulose fibre smoother than cotton that does not pill after washing and feels cool against the skin. It is a comfortable choice for all-day wear and for skin that reacts to rougher fabrics.

Worth checking too

Soft bras work well for everyday wear, for travelling and for sleeping. If you want a smooth line under a thin blouse, reach instead for a padded model - a soft cup does not conceal the nipples.

Delivery and returns

Many models belong to ranges with a matching bottom, so a set is easy to put together. Choose your size by your underbust measurement and cup letter; if your size is unavailable, check the sister sizes. Wash in a bag at 30 degrees. Free delivery from PLN 199, 60-day returns.

What to look out for

If you want a set, check the range name in the product title - the bottom in the same pattern is usually listed under the same name.

In terms of construction, the selection splits roughly into three parts. Models with an underwire and a moulded cup give a smooth line under thin clothing. A dozen or so items are wire-free constructions with a soft cup and a wider band, more comfortable across a whole day. The rest are intermediate versions, with light reinforcement in the lower part of the cup. Polyamide with elastane dominates the fabrics, along with lace stitched into the upper cup panel.

This collection brings one brand's bras together in one place, in bands from 70 to 105 and cups from B to E. More than half the models have matching briefs from the same range, which lets you build a set without hunting blindly for pieces across different collections.

When choosing a size, do not carry a number over from another brand without checking. Every manufacturer distributes volume differently between cup depth and cup width, and the biggest differences show up precisely around the underwire under the arm. Measure your underbust on the out-breath and your bust at its widest point, then compare the result with the chart for the specific model.

If you are also looking for knickers, vest tops and the brand's other categories, you will find them in the Sielei collection. We have gathered ready-made sets in lingerie sets, and our size guide will help you turn measurements into sizes.
