It's very normal for a 3 year old to not want to wear clothes as many 3 year olds resist wearing clothes or prefer being undressed.
My 3 year old would always get undressed when we got home and would strip down to his diaper and sometimes he would even take his diaper off but thankfully most times he kept it's diaper on.
It's very normal behavior and if they are not going anywhere it's okay let the 3 year old just be in their underwear or diaper but when out in public they need to wear clothes.
Most 3 year olds and toddlers have a strong preference for comfort and may not understand that they need to cover up, especially if the toddler has a natural acceptance of their body.
A 3 year old or toddler not wanting to wear clothes can also be influenced by sensory sensitivities or even just a simple desire to test their boundaries.
Shedding clothes is normal for toddlers and 3 year olds and is a way for them to declare their independence and test their boundaries.
To get your 3 year old to dress make getting dressed fun for the 3 year old and also offer choices between a few acceptable outfits and keep the choices simple and appropriate for the weather.
You can also incorporate the 3 year olds input and let them pick out what they want to wear, either in the morning or by having the 3 year old select outfits the night before.
You can make it fun for the 3 year old to get dressed by doing silly games, using timers and music and even focusing on undressing before dressing to build the 3 year olds confidence.
Also don't rush the 3 year old when getting dressed and praise the 3 year old when they do get dressed on their own in a timely manner.
You can also use a reward system for consistent behavior when getting dressed like the use of stickers or allowing extra playtime and you can even play dress up together if possible you can get dressed alongside them.
To teach your child or toddler to dress themselves start with easy to put on and take off pants and shirts and avoid pants and shirts with buttons.

Then have your child or toddler try putting his pants on themselves and if they need some help go ahead and help them and continue to have them try putting his/her pants on themselves.

Make time for the child or toddler to regularly practice putting on their pants and taking them off and don't rush the toddler or child and allow them time to learn.
You should also demonstrate to the child or toddler with slow and deliberate movements to show the child or toddler how to pull their pants up and down and exaggerate the movements to make the movements easier for the child or toddler to follow.
