Yes that is true.. although from a secular point of view sort of defeats the purpose of covering.

And actually so much colour and creativity could be brought into the islamic world where we can cover up and still suit our islamic requirements. It really gets me that religious women seem to limit themselves to black, black and more black.. thrown in with the occasional navy blue. I mean.. I would think these colours too hot to wear in the desert.. I'd much rather wear colours that complement my skin tone and feel comfortable to wear. As well as make me feel like a princess with the soft and luscious fabrics.. oh la la..

According to the correct opinion (one with the most evidence) is that a women can wear any colour of clothing. And that it can be beautiful as long as it meets the islamic criteria.. of not being see through, too tight, and worn to attract others or have a higher status from the people.

 and in fact, the person who has wealth is able to spend on good quality and beautiful clothing. According to a hadith of the Prophet Mohammad SAW.
