5 Best Necklines for Small Busts

1. Sweetheart Neckline: best for a romantic look

A sweetheart neckline gets its name from depicting the curves at the top of a heart. Not only is this neckline super flattering, but it's extremely romantic. Sweetheart necklines are very open and show lots of skin, specifically your collar bones and shoulders. A sweetheart neckline can be one of the best necklines for small bust because it can accentuate the bust making it look fuller and whole. The curved shape also draws the eye upward and can help elongate your neck.

This top from Jonathan Simkhai is a great option.

2. Tube Top: best for showing off your collarbones

Tube tops can be a great way to dress a small bust, specifically ones made from spandex material. This way your boobs can get that extra lifted look while accentuating your collar bones and shoulders. Go for a fitted tube top and skip loose fabric along the chest, since it won't sit as nicely on a small bust.

Bows are a trend this 2024 and we're here for it.

3. Narrow V-Neck: best for the illusion of a fuller bust

Narrow v-necklines are great necklines for small busts because it gives off the illusion of having bigger boobs. On the right you can see a dress with a wider and more broad v-neckline showing too much chest and making her boobs look separated and smaller. On the left, you can see a more narrow v-neckline showing less chest and an illusion of bigger boobs.

4. Halter Neck: best for broad shoulders

Halter necklines can be one of the best necklines for small busts because it showcases your shoulders, drawing the eyes upward. If you're someone who is petite with broad shoulders, halter necklines can be a great way to balance your top half of the body as a whole. Halter tops are also a great way to showcase your arm muscles, again drawing the eyes away from the chest and to other parts of your body in a very tasteful way. A fitted halter can also help define your waist for a more balanced silhouette.

Amazon has a ton of affordable halter tops that are super cute. Check out more of them here.

5. Boat Neckline: best for showing less skin

A boat-neckline is a horizontal line across the collar bones. The horizontal line adds more emphasis around the neck and shoulders, which works so well with a smaller bust. Most women with larger chests actually avoid this neckline because it makes them look bigger than normal. If you're looking to not show a lot of skin but still give your body shape and spice, a boat neckline is for you.

I have this and it was very flattering on my small bust. Comes in other shades too.

More Style Tips for a Small Bust

Get the right bra. A bra that fits properly is more comfortable and helps your clothes fit better, so it's worth getting fitted. Here's my guide to lingerie for small busts.

Try a sticky bra or breast tape. A sticky bra uses silicone or gel for a natural, subtle lift without extra padding, and it works under low-cut tops and dresses.

Highlight your waist. Belt a dress or pair a fitted top with high-waisted pants or a skirt.

Layer. Try a fitted top under a flowy cardigan or a blouse under a bralette, and skip layers that are too baggy. More ideas in how to layer crop tops.

Pick cut-outs in proportion. Cut-outs add interest and draw the eye to other parts of your body. Just avoid ones that are too large or too revealing.

Go monochromatic. One color from head to toe creates a streamlined, elongated look.

Try a corset made for a small chest. Our Venus Corset has small, extra-padded cups made mostly for small chests.
