Yes, as said it doesn’t mean you look bad, but I think this is the issue you are seeing, it’s muscle loss or lack of muscle, and you fundamentally will look a million times better than before you lost the weight,
i cant stress how important muscle is at our age, and for anyone reading it is critical to protect during the weight loss phase.
so I’d recommend getting into strength training, it will improve your posture, the definition on your limbs, and stomach.
it’s critical for our health, but if you wish to improve appearance when naked or in swimwear, then building muscle is the way to do it.
for women it is incredibly hard to bulk up, what it gives us is that long lean look.
so id focus on protein intake, as you need to build take 1.5g per kg of body weight min, start strength training, either book a pt at the gym to show you or use an online tutorial like Caroline girvan, lift heavy lower reps is for strength, lower weight, higher reps is for stamina/endurance, so aim for mid range.
if you do this, you will look incredibly different by your holiday next year.
good luck, it’s work but worth it.
