No I think it's fine. If it is quite hot where you live, I can understand that. This one is nice, and is great for a date in my opinion. Here it's winter so I haven't seen this type of dress since 5 or 6 months lol! Just be careful about how you stand and sit, otherwise it can look a bit weird. Just go for it!
Honestly... On me that would look like a shirt. I have a long torso and long legs so that would be all types of wrong on my body😂 I don't know how tall you are or what your body looks like, but if it's not made into a shirt, fits nicely, and goes like 4-5 inches below your butt, I'm sure your fine.
