Where you daven. (and if you don’t have a set place, PICK ONE, ASAP) as that will enable people to see you in your best setting. Especially, if you’re still in yeshiva, as when anyone goes to scope you out in the BM, you are among 100+ guys just like you.
At this point in life, you want to be the focus of attention, not part of the herd.
Personally, I would scratch “height”. Its (IMHO) irrelevant, both on your part and on hers. Weight, you can (to some extent)control, height is a fact.
