Yes, you can be hotter overnight.
Iron or steam your clothes.
There's a huge different between wrinkled clothes and their ironed or steamed counterparts. This simple thing can mean the difference between looking well-dressed and sloppy. T-shirts aren't an exception either, a few swipes with an iron can upgrade your look almost instantly.
Ditch the boxers.
Boxer briefs are more stylish and offer your junk support, unlike boxers. Opt for a classier boxer brief, or if you're really feeling free try a brief. Boxer briefs tend to not bunch up as much as regular boxers and you won't get that dreaded "moose knuckle."
Find a good tailor.
Finding a tailor for suits, jeans, jackets, and other garments is crucial and will make a big difference in making sure you look super sharp. You don't need to get everything tailored, but if you grab a suit off the rack, you'll probably want to get it fine-tuned at your local tailor.
Make sure all your clothes fit.
If you have a smaller frame but you've been wearing medium all your life, give the small a try and see if you look better in it. The same advice applies for all body types.
