A burkini... is a type of modesty swimsuit for women... the suit covers the whole body except the face, the hands and the feet, while being light enough for swimming. -- Wikipedia
Looking online, there's a range of different burkini styles around. Some seem to aim to cover the awrah of a woman (in front of men), while some are more practical for swimming (a kind of compromise solution, or perhaps better suited for swimming only with women).
Question: What should a Muslim woman look for in a burkini?
There seems to be a bunch of problems with burkinis:
- They incompletely cover the awrah.
- They are skin tight, or become so when wet.
- They inhibit swimming.
- They are potentially a drowning hazard.
Edit: I tried some conservative swimwear I bought in Turkey. I can confirm 1., 2., and 3.; basically it's like swimming while wearing everyday clothes. And 4. is a logical conclusion from 3. From my experience, I can also add:
You draw attention to yourself by looking different (assuming not all women are wearing them).
They're difficult to change out of when wet.
