Best Bras for Gaping Cups
Cups that wrinkle or gape at the top are holding space your tissue doesn't fill. These picks fix it with lower top edges, stretch upper panels, and shallow-cut cups - not by squeezing you into a smaller band.

Gaping cups have one root cause: the top of the cup is cut for more upper fullness than you have. That happens when the cup is simply too big, and it happens at the RIGHT volume when your shape is shallow or fuller on bottom - the tissue sits low, the rigid top edge stands empty. Two fixes work. First, try one cup size down (keep the band). If the smaller cup overflows at the bottom while the top still gapes, the cup volume was right and the SHAPE was wrong - switch constructions: demi and balconette cups end below the gap line, and stretch-top panels collapse to sit flush against whatever fullness is there. Every pick below uses one of those constructions and is in the BraFinder catalog now.

Detailed Reviews
Wacoal Shape Revelation® Shallow Top Underwire T-Shirt Bra
Wacoal · Bands 32-40, cups B-G · $45.60
The rare bra designed for the exact shape that gapes: the upper cup is cut shallower so it lies against low-sitting tissue instead of arching over it. If every 'right size' bra still wrinkles at the top, this construction is the fix.
What we like:
- Cup engineered specifically for shallow upper tissue
- Smooth t-shirt finish under fitted tops
- Solves gaping at the construction level, not with padding
Watch out for:
- Limited to a G cup
- Muted color range
ThirdLove Rose Lace Unlined Demi Bra
ThirdLove · Bands 32-42, cups A-I · $79
Unlined plus demi is the gap-fighting combination: no molded shell to stand empty, and a lower top edge that stops before the space your tissue doesn't fill. The soft lace top edge flexes with you through the day.
What we like:
- Unlined cup drapes to your actual shape
- Demi cut ends below the usual gap line
- Wide A-to-I cup range
Watch out for:
- Premium price
- Lace shows under thin knits
Glamorise Front-Closure Stretch Lace WonderWire Bra
Glamorise · Bands 30-48, cups B-G · $39
The stretch-lace upper third does what a rigid cup can't: it contracts to sit flush on less upper fullness and expands on more. A forgiving choice if your fullness changes through the month.
What we like:
- Stretch-lace upper panel adjusts to your fullness
- Bands to 48 - rare at this price
- Front closure is easy on shoulders and hands
Watch out for:
- Lace look isn't for everyone
- Cups stop at G
Panache Cherie Demi Bra
Panache · Bands 28-38, cups DDD-I · $33
Full-bust shoppers gape too - a G cup that's fuller on bottom stands empty at the top of a full-coverage cup. The Cherie brings the demi fix to DDD-I cups, ending the cup where shallow-top tissue actually stops.
What we like:
- Demi coverage in genuine full-bust sizes
- Bands from 28 for narrow ribcages
- Strong value at $33
Watch out for:
- Band range stops at 38
- Starts at a DDD cup
Panache Tango Balcony Bra
Panache · Bands 28-44, cups D-O · $32
A balcony cut carries the horizontal, lower top edge that shallow and bottom-heavy shapes need, and the Tango offers it across one of the widest size ranges in the catalog. At $32 it's the low-risk way to test whether balconette ends your gaping.
What we like:
- Balcony neckline sits below the gap line
- Huge range: bands 28-44, cups D-O
- The budget pick at $32
Watch out for:
- Full-bust focused - starts at a D
- Simple styling
b.tempt'd Untamed Demi Underwire Bra
b.tempt'd · Bands 32-38, cups B-DD · $50
Gaping isn't only a full-bust problem - a shallow B or C gapes in molded full-coverage cups too. The Untamed demi covers the smaller-cup side of the fix with a low top edge and soft materials that follow your shape.
What we like:
- Demi cut in B-DD cups
- Soft, flexible cup materials
- Modern styling
Watch out for:
- Narrow band range
- Not for full-bust sizes
How We Evaluate
Every bra on this list was evaluated on the same criteria:
Top-edge height
The gap lives at the top of the cup, so we favor demi, balconette, and shallow-cut constructions whose edge ends below it.
Flexible upper cup
Stretch panels and unlined fabric settle against your actual fullness; rigid molded shells hold the empty shape that wrinkles.
Shape match over size change
Gaping at the correct volume is a shape problem. We pick for shallow and fuller-on-bottom shapes rather than telling you to size down twice.
Size honesty
Every pick's bands and cups come from the live catalog, and the range printed is the range actually stocked.
Choosing by Cup Size
B to D: Skip heavily molded t-shirt cups - a shallow B-D does better in a soft demi like the b.tempt'd Untamed or an unlined cup that drapes.
DD to G: This is where the Wacoal Shape Revelation and Glamorise stretch-top earn their keep: shallow-cut or flexible upper cups at real mid-range volumes.
H and up: Go demi or balcony cut in true full-bust engineering - Panache's Cherie (to an I) and Tango (to an O) end the cup below the gap while still supporting the volume.
Frequently Asked Questions
Why do my bra cups gape at the top?
The top of the cup is holding space your tissue doesn't fill. Either the cup is a size too big, or the volume is right but your shape is shallow or fuller on bottom, so tissue sits low and the rigid top edge stands empty. If sizing down one cup causes bottom overflow while the top still gapes, it's the shape - switch to demi, balconette, or stretch-top constructions instead of chasing sizes.
Should I size down if my cups gape?
Try one cup size down first, keeping your band - that fixes simple oversizing. But if the smaller cup digs or overflows at the bottom while the top still wrinkles, stop: your volume was right and the construction was wrong. A demi or balconette in your original size will fit better than a smaller full-coverage cup.
What bra styles are best for shallow breasts?
Demi and balconette cuts (the top edge ends below the gap line), stretch-top cups (the upper panel collapses to your fullness), and purpose-built shallow constructions like Wacoal's Shape Revelation. Avoid tall, rigid, full-coverage molded cups - they're cut for upper fullness a shallow shape doesn't have.
Can I fix gaping cups without buying a new bra?
Partly, sometimes. Tightening the straps lifts the cup closer to low-sitting tissue, and shortening the band (a smaller hook setting) can improve contact. But if the cup's top edge is rigid and cut tall, no adjustment removes the empty space - the honest fix is a lower or stretchier top edge.
Do gaping cups mean my bra is too big?
Not necessarily. It means the TOP of the cup is too big for the fullness that sits there. Overall volume can be exactly right - common for shallow and bottom-heavy shapes, where a 'perfectly sized' full-coverage cup still wrinkles. Match the construction to the shape and the gap closes at your true size.
