Breast shape.
Two people can be the same size and need different bras. Shape is a big part of why — and why The Cupsar lets you compare reviews from similar shapes.
Why shape matters
Size tells you roughly how much volume a bra needs to hold. Shape tells you where that volume sits and how it's distributed — and that changes which bras actually fit. The same size can fit very differently across different shapes.
Shape affects cup depth, wire comfort, whether the gore tacks against the sternum, gaping at the top edge, cutting in, and how much a cup projects. Two reviewers in the same size can have opposite experiences in the same bra because their shapes differ.
These labels are approximate, not identity labels. Most people are a mix and don't fit one category perfectly. Pick the closest one, use OTHER if nothing fits, or leave it blank if you're unsure — it's always optional.
The shape options
Round
Fairly even fullness top and bottom. Tends to fill a range of cup styles without much gaping.
Teardrop
Less full at the top, fuller toward the bottom. Often does well in styles that aren't cut high.
East west
Nipples and fullness point outward, away from the center. Wider wires and styles with side support can help.
Side set
A wider gap at the center, with tissue set further apart. Center gore and wire width matter more here.
Close set
Little gap at the center, tissue set close together. Narrow gores and centers can feel crowded.
Wide set
Roots sit further apart on the chest. Wire width and gore width are usually the deciding factors.
Asymmetric
One side is noticeably different from the other in size or shape. Fit is often judged by the larger side.
Center full
Fuller toward the center of the chest. Plunge and lower-center styles can suit this well.
Full on bottom
Most volume sits in the lower half. Styles cut lower or with less top coverage tend to gape less.
Full on top
Noticeable fullness in the upper half. Higher-cut styles and firmer top edges can help avoid spillover.
Shallow
Volume spread over a wider area with less projection. Shallow or stretch cups usually fit better than deep ones.
Projected
Volume concentrated forward with more depth. Deeper, more projected cups reduce cutting in and gaping.
Athletic
Firmer, often wider tissue with less projection. Wire width and a supportive band are common fit points.
Other
If none of these fit, OTHER is fine. You can also leave shape blank if you're not sure.
Using shape in reviews
When you filter by shape, you're narrowing toward reviewers whose volume sits like yours. That won't tell you a guaranteed size, but it makes fit problems easier to read — a pattern of gaping or cutting in among similar shapes is a stronger signal than a single review from someone shaped differently.
