Question:

1.must a woman dress tzniyusdik while Davening or making a bracha

2.are Starbuck frappucino kosher

Answer:

1. When we daven we are standing in front of H-shem and talking to Him. Therefore everyone, men and women must not only be dressed tzniusdik, but we must also be dressed in a respectable fashion. Regarding making a bracha- a person should be clothed correctly when bentching, regarding brachos it is preferable to be properly dressed.
2. Regarding your second question, I would suggest that you call the OU directly at 212-613-8241.
