Birthday outfit #1: "The little man"

One of my all-time favorite looks for a little boy is a “men’s” polo shirt and a pair of jeans.

LEVI’S SLIM FIT JEANS

GRAY CHUKKA BOOTS

We own this entire outfit, so I can tell you from first hand experience that it’s adorable and all of the items are high quality.

Even though Lacoste shirts are luxury items, they often go on clearance in the exact size you need for a 1 year old, so you’re in luck!

BUYING TIP:  To see the Lacoste polos that are on sale, be sure to select SIZE 1.

Then check the different colors to see which are discounted the most.

If you can find any colors you like for less than $22, it’s a GREAT deal for this premium brand.

Aden wears his gray chukka boots all the time and we constantly get compliments. 🙂 I’m planning to buy them again when he outgrows them.

Now let me tell you about the baseball cap.

Here’s why I love it this hat:

1) No ugly writing or labels! WHY oh why are baby boy’s clothes always covered in words or dinosaurs?!

2) The quality is great and the price is quite low. I’m talking less than 10 bucks low.

Even if your son doesn’t end up wearing this cap on his first birthday, it’s a wardrobe staple he’ll use 100 times in the future. See it here.

Now for the next *adorable* baby boy’s birthday outfit…

First birthday outfit #2: "The little hipster"

Especially if your baby is turning one in the fall or winter, this little outfit is to die for!

The brown Carhartt hat is widely adored and actually quite trendy at the moment. (20,000 reviews don’t lie!)

BUYING TIP: If your baby has a small or average sized head, get the TODDLER sized hat.

If he has a large head (or you want room to grow), get the YOUTH size.

Now I have to tell you about the leather moccasins.

I bought them on a whim when Aden was in the very early stages of walking. Actually, he was mostly crawling and I needed something to protect the tops of his feet.

They’re the best.

These leather mocs check several boxes for me:

1) They only take 2 seconds to put on, thanks to the elastic.  (Toddler shoes are notoriously difficult).

2) They’re soft soled, which is what’s recommended for new walkers.

3) They’re stylish and real leather!

4) The price is right.

See a real customer’s pictures of the moccasins here.

On to our next 1 year old birthday outfit…

First birthday outfit #3: "The wild one"

This casual look is perfect for an untamed little dude.

Most first birthday shirts are worn once and then they become pajamas or donations.

But this adorable Wild One t-shirt is cute for daily wear beyond your son’s first birthday party.

I love the black, but check out the other colors (and styles)!

P.S. This birthday shirt would also look great with a pair of distressed jeans, if you happen to already own a pair.

Ok, ready for another handsome 1 year old boy birthday look?

First birthday outfit #4: "The classy mini man"

Your baby boy will look like the perect gentleman in this sophisticated outfit… until he sticks his face in the cake, that is.

GRAY SKINNY CHINOS

I’m obsessed with this look from head to toe! It’s really easy to recreate in different colors, too.

For less than 10 bucks, those chino pants are an absolute steal.

You may even want to grab a few pairs in future sizes.

They work best for a baby or toddler who is tall and slim.

See how they look on this adorable little boy.

And now for one last 1 year old birthday outfit! …

First birthday outfit #5: "The trendy cutie"

You can’t go wrong with this VERY popular color…

“COFFEE” LONG SLEEVE SHIRTlong sleeve brown shirt

boots for one year old

UGG CHUKKA BOOT

This long sleeve shirt is a STEAL. I was shocked to see how thick the fabric was when it arrived in the mail.

The color is super on trend this year. Online boutiques are selling similar brownish neutral toned solid color shirts for twice the price.

The “1T” size was perfect for Aden at 12 months old.

If you’re on the fence about what size to get, definitely size up. See the sizes here.

A few more favorites for a 1 year old boy

While you’re grabbing your little boy’s first birthday outfit on Amazon, check out these 3 other items that I love.

  • Grippy low-cut socks: If your almost 1 year old has outgrown all his baby socks, get these—they’re the best.
  • 2-piece pajama set: Out of all of the pajamas we own, these have held up the best. The material is thick and the black doesn’t show stains. They also come in pretzel or popcorn designs!
  • Baby/toddler sunglasses with strap:  These are genius. They’re sturdy, flexible, and best of all they stay put!

Final thoughts on choosing your baby boy’s first birthday outfit

First some general advice:

Remind yourself that it’s 100% okay if your son’s first birthday doesn’t go perfectly.

It will still be memorable… even if the weather sucks, your baby is in a bad mood, your family isn’t getting along, and so on.

Que sera sera… whatever will be, will be…

The same goes for what your baby boy wears on his birthday.

Choose something cute for pictures—but expect that it will get dirty quickly. (If it doesn’t, you’ll be pleasantly surprised!)

Plan a backup outfit—something you won’t mind seeing in lots of pictures—but don’t overthink it.

Your son’s handsome face, which may soon be covered with cake, will be getting all of the attention, anyway!

And hey, worst case you ditch the “first birthday outfit” and let him wear his “birthday suit”! 😉
