What do I wear to look nice without trying too hard?

I'm on a rapid weight loss plan, and a year ago, I had professional photos taken, and thats what ultimately pushed me to take initiative that my body was so fat, that even if I wore something really nice, I'd be insecure. I scheduled another photoshoot the same time this year, in the fall, and I don't know how much weight I would have lost, but I'd probably be under 200 lbs to the maximum 160 lbs if it went the way it was going now, and for my height it's not a bad thing at all to be that much, it looks great, but I don't know because my arms are still the same, and my thighs are still cottage cheese like and I feel like I'll hide my body cause I just have jiggle. I know I can lift weights and I have been, but I know I'm battling years of not having definition to suddenly striving for it. Sigh, I just wish i could see myself where I liked everything. So do you have any thoughts on a theme I could pick thats not too in your face but nice?
