Our Monroe shape is designed to fit C-E cup busts.

Not sure about size?
  • This style is shorter in the body length. If you are long in the body, we recommend going up a dress size. For a fuller fit on the bottom we also recommend going up a dress size. 
  • Features luxe under-bust elastic for lift and shape.
  • Medium, flattering cut on the leg. 
  • Our Monroe model Berry usually wears a UK size 12 on top, a size 14 bottoms and a 32D bra. Shown here wearing a Deakin and Blue size 12 Monroe. (She's sized down for a cheekier fit on the bottom).
  • Super soft, high quality, sustainable Italian Lycra®.
  • Made from recycled yarn ECONYL® from regenerated waste such as old fishing nets and industrial plastic scraps.
  • Soft, stretchy, light and breathable. Perfect blend of muscular compression and comfort.
  • Durable and designed to last. Twice as resistant to chlorine, salt water and oils than standard Lycra. Full UV protection.
  • Designed and manufactured responsibly in London, UK.
  • Rinse after every use and hang to dry. Machine wash at 40° after every 2-3 uses. See full details on how to care for your swimwear.

    Xback swim suit plum , munroe

    I couldn’t be happier with the swimsuit I ordered and had lots of fun swimming feeling comfortable and secure. I really wish I had bought one before now

    Better than expected

    After umming and ahhing for several weeks I took the plunge (metaphorically) and placed my order. I had high hopes after reading all the great reviews but even so was so very pleasantly surprised when I tried the swimsuit on and it looked and I felt great! After years of feeling conscious in poor fitting cossies I can’t wait to properly try it out.

    Love it!

    Absolutely love this swimsuit. Fits well in the boob area while not being too long in the body (something I struggle with being vertically challenged with excess body in the upper frontal region!!) I swim a few times a week but going on holiday soon so will almost certainly need more swimwear for that!

    Very pleased with my new suit

    I was quite skeptical before buying - I have always bought Speedo in the past and wasn't sure if my new swimsuit was intended for pools as well as oceans. However, I am really pleased - very high quality, great fit and colour (plum).
