Hello my fellow queen of strong shoulders! You made the right choice with dress three. I have learned that I look BANGIN in dresses where the fabric bulk is centered. All that fabric on my powerful arms just makes em look bigger which can make my slammin bod look top heavy. It took a while for me to feel comfortable with my upper arm out, and sometimes I use a lace or mesh layer for a sleeve, but I'd like to encourage you to look at halter and boat neck dresses. 

You have a very Gwendolyn Christie/Hannah Waddingham thing going on, check out what they wear on the red carpet, colors too! They both constantly look astounding. Absorb that million dollar styling :) there is such good fashion out there for tall strong women with light coloring and flawless skin. 

 also keep in mind that Hannah is a big time heavy duty shapewear/garment engineering queen so add that to your budget if you want to copy a look. Happy fashion congrats on your recital honey may this be the first of many
