Bra Fitting

It is estimated over 80% of woman are wearing the wrong bra size.

Finding the right bra size and shape can make such a difference to your shape and of course, your confidence!

How to measure your bra size:

Measurements should be made on skin not over clothing.

  1. First measure around your body directly under the bust, this will give you the underbust measurement.
  2. Measure around your body over the fullest part of your bust this will give you the over bust measurement.
  3. Refer to our chart, your bra size can be found where the two measurements intersect.

This bra size guide should help you to generally determine the right bra size and is pretty accurate, but we recommend that you try on a variety of styles to determine the best bra size and style for you.

Remember, Bedtime Flirt offer a no quibble returns policy so you can shop with us with confidence safe in the knowledge that if you buy a bra in the size you think is correct for you, but if it doesn't fit, you can return it to us for an exchange or refund.

Bra fitting tips

  1. The underband of your bra should fit comfortably in the middle of your back and not rise up or down.
  2. The underwire should never dig into your breast tissue and should fit snugly under the arm.
  3. The underwire should lay flat against the breastbone.
  4. The bust should not spill over the top of the cup. If it does you are wearing the incorrect cup size.

Size Guide

Most of our lingerie is available in Small, Medium, Large, etc. Please refer to the simple size chart below to see how standard sizes relate to our easy-to-choose size range across many of our products. Some products are "One Size" giving a very comfortable fit for UK sizes 8-12.

When purchasing a corset we recommend you buy the same size as the band size you normally wear on a bra, for example if you are a 34B you should purchase a size 34.

Lingerie Care

Here are a few tips on how to protect and care for your beautiful new lingerie.

We highly recommend hand washing all of our lingerie in gentle soap flakes, hand washing liquid or a neutral shampoo. Do not use bleach or any whitening products.

Wash dark, light & coloured fabrics separately.

Wash hosiery separately as bra hooks & fastenings can catch. Allow to drip dry over a bath or shower. This should substantially lengthen the life of your hosiery.

Try not to wear light lingerie under dark clothes or denim as this can dull & dye delicate fabrics instantly.

Do not tumble dry lingerie as this may damage the delicate fabrics.
