If you are comfortable in this dress - can sit without showing too much thigh (or crotch!), will not be tugging at the off shoulder or pulling it up, your strapless bra works and will not show, AND you are thin enough to pull it off without heavy duty spanks, then I think it will work. One shoulder stuff is very popular.
I think a simple, classic black dress is called for at this pref round. And, technically, this is just that. This dress is, however, a style that can be uncomfortable.
Just my opinion! Some of the GC Texans may differ and I defer to them.
