All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
May Allah reward you for your keenness on wearing Hijab (the veil), and we ask Allah the Almighty to increase you in guidance, piety, and righteousness, and to protect you and preserve your religion for you.
You should know that one of the most important purposes of Islam in legislating Hijab for a woman is to cover (dress up modestly and cover her entire body) and avoid everything that leads to temptation. Therefore, the jurists stipulated certain conditions for the clothes of women, such as: it should not be ornamented, and this condition is not fulfilled in the dress that you described. The same thing applies to the lower part (the sheer part), because it may lead to temptation, even if you wear loose pants under it.
However, if there is an urgent need to go out and you cannot find any dress except this one, then it is permissible for you to go out for such a need, and the need is valued according to its proper value. Once the need is fulfilled, you should return to your home.
For more benefit on the evidence for Hijaab and its conditions, please refer to Fatawa 81554, 83765, 83702, 81494, 354259 and 83033.
Allah knows best.
