Should Your Crew Neck Undershirt Show Under Your Sweater? 👍 or 👎?

Is it a fashion disaster to have your undershirt showing when you wear a crew neck sweater? Here’s a fun style-related question from a reader who is worried about breaking a style rule.

Hi Tug,

When I wear my crew neck undershirt under a particular crew neck sweater, the undershirt is exposed at the neck.

As such, does this mean my sweater has too large of a neck hole, or my undershirt has too small of a neck hole?

Is it acceptable for the undershirt collar to be showing?

How To Wear A Crew Neck Undershirt Under Crew Neck Sweaters

Heya Bob,

Good to hear from you and a great question indeed!

To be really honest, I don’t think it means your sweater is too large or your undershirt is too small, but it does present a style quandary.

If you’re going to stick to a crew neck style t-shirt or undershirt, here are my recommendations.

DO Match Your Undershirt or T-Shirt Color With Your Sweater

If you’re going for a layered look, I’d suggest mixing it up by finding a crew neck undershirt that matches or contrasts nicely with your crew neck sweater. You could also wear a heathered grey undershirt, which matches nicely with most other colors.

A stark white undershirt can only match certain colored sweaters. Wear a white undershirt with white, cream or beige colored sweaters for best results.

DON’T Forget To Tuck Your Shirt In

Making sure your undershirt stays tucked can be a challenge. Choose a slim-fitting undershirt that hugs your body, so you can avoid bunching and adding bulk under sweaters. 

DO Choose An Undershirt With A Larger Neck Opening

Do you prefer a clean, unlayered look? You’ll need an undershirt or lightweight t-shirt that has a larger neck opening that won’t show at all.

Consider either a scoop neck or wide-neck undershirt like what Ryan Gosling wore in the movie Only God Forgives.

DON’T Worry About Showing A Little Collar

Don’t change a thing if you don’t bother about showing a little collar at the end of the day. In fact, white undershirts actually look good stylistically under a crew neck sweater.

DO Wear An Undershirt If You Need To Stay Warm

An undershirt can add an extra layer of warmth and protection. So whether you’re wearing a dress shirt or a sweater, this additional layer can be a lifesaver if you’re cold or prone to sweating.

Summing It Up

Hope that information helps buddy.

  1. Hi Tug,

    I find its very complicated now to wear an undershirt. Yes for comfort, yes for protecting our shirts, yes for absorbing body oils and perspiration. For all these reasons we wear an undershirt. But in 2021 we must not see it anymore!

    It would take the invisible….Women wear bras they are visible under their blouses and no one takes offense. What’s wrong with men today, should we be more feminine than women? A guy is a guy and wears guy’s underwear, what is the problem ?

    I am a sophisticated guy who loves fashion and beautiful clothes. I buy designer and expensive clothes that I wear with pride. But that won’t stop me from wearing undershirts and I don’t believe they affect my look.

    If you bought a good fit undershirt (second skin style) of good quality not change your look. Its not similar with these cheap undershirt too large and no style. Please, let’s stop making life more complicated.

  2. This is a great casual, relaxed look. Not a problem at all, but you can polish it up a bit by taking Tug’s suggestions and wearing a matching colored undershirt or one that doesn’t show. It all depends on the setting and what you want to convey about yourself and your sense of style.

  3. Personally my wife loves my look when i have a hint of my undershirt under any shirt. Makes her want to rip my clothes off, so all is good!! ;)

  4. I wouldn’t worry too much about it, an undershirt peeking underneath makes a great layering look. If you’re really worried about it showing- I would opt for V neck or an undershirt with a wider or lower neck as mentioned but again, nothing to lose sleep about :)

  5. I wouldn’t stress over it. It’s OK to show some shirt. I personal have worn crew tees under crew and v neck sweaters. It’s not something that will detract from your look. I only recommend going without a tee in warm weather where you’re expected to show more skin and want to avoid overheating. Stay stylish!

  6. This is a good thing. Part of your shirt should always show underneath your sweater at the neck opening, 1.) because layering is good, and 2.) if it doesn’t, it looks like you’re wearing a sweater with no shirt on underneath, and that’s weird.

    Don’t think too much about it.
