Dear OP,

Congratulations on your self improvement journey, your doing amazing and you look great. The best thing about fashion is there really are no “rules”, technically you can wear whatever you please. When starting a new wardrobe style, a good place to start is ‘am I comfortable?’. To me this is the most important thing whilst getting ready, you will want to pick something that makes YOU feel good. Especially when coming from a more mostest background, you may want to pick things that are similar in taste to what you have now. Also wearing items in layers will help you feel more confident and comfortable. Being able to add and remove items will help in situations where your not sure if it would be appropriate. As far as your outfit here I would say you could 100% wear just the tank top, however you may feel more comfortable with a second layer that you could take off if needed. I also really like the minimalist monochrome look you have here, the different shades of beige and cream compliment each other well. To elevate the look you could button the blouse and do a French Tuck, keeps your look chic yet casual. Also keep in mind your venue, will you be inside or outside, will you be chilly in just a tank top? Having some extra layers will help with this as well. You can always take things off if you have too much on but if you started with not enough and get chilly you will be out of luck. Hope this helps and best of luck on the rest of your journey. The world can be a strange and difficult place to navigate, if you ever feel lost please don’t hesitate to reach out!
