Puff sleeves may be too much for tiny ladies, but there's no reason you shouldn't try them. You may choose less voluminous, subtler puff sleeves so you don't feel like you're drowning in the garment. Shorter dresses would also be quite seductive, and the puff sleeves would be perfectly balanced. The same goes for men. If you are worried about appearing too small or skinny, then by all means let your arms be seen! Long sleeve shirts are easy to roll up, and short sleeves are perfect if you want to show off your defined biceps. As long as you aren't making yourself look ridiculous, go for it!
