Full on Top vs Full on Bottom Breast Shapes: The Ultimate Bra Guide with Style Recommendations

Full on Top vs Full on Bottom Breast Shapes

Understanding whether you're full on top (FOT) or full on bottom (FOB) can transform your bra shopping experience. FOT breasts have more volume in the upper and above-the-nipple portion, often looking perkier with fullness high up. FOB breasts carry more tissue lower down at and below the nipple, creating a fuller bottom curve and sometimes less upper fill. Both of these are describing your breasts as they naturally are with no support.

The right bra style—plunge, balconette, full coverage, half-cup, or demi—makes all the difference. FOT thrives in lower-cut, open-top styles like balconettes and plunges for room up top. FOB needs deeper bottoms and more coverage, like full cups or supportive plunges with immediate projection.

General Notes:

Fit varies by size too. Smaller busts generally have more style flexibility (lucky ducks!), while larger ones typically benefit from more structured support.

Always prioritize "scoop and swoop" technique and check wire width/root fit. Always try on with your usual clothing, assess in multiple positions (standing, leaning, arms raised), and remember to use sister sizing when helpful. (Size ranges are approximate based on common availability; actual range varies by color/style and current availability.)

For FOT, prioritize open necklines like balconettes and plunges with side support to contain upper tissue—check that the top edge sits flat without cutting in and that you have no spillage when leaning forward. Stretch lace tops are a big help for FOT shapes!

For FOB, seek styles with firmer side/bottom construction, deeper lower cups, molded or stretch tops, and push from below to avoid gaping—scoop and swoop thoroughly, ensure the wire follows your breast root fully at the bottom, and verify the upper cup lies smooth without wrinkles or empty space.

Final Tips for FOT and FOB Success

For FOT, prioritize open necklines like balconettes and plunges with side support to contain upper tissue—check that the top edge sits flat without cutting in and that you have no spillage when leaning forward. 

For FOB, seek styles with deeper lower cups, molded or stretch tops, and push from below to avoid gaping—scoop and swoop thoroughly, ensure the wire follows your breast root fully at the bottom, and verify the upper cup lies smooth without wrinkles or empty space.

Always try on with your usual clothing, scoop and swoop, and assess in multiple positions (standing, leaning, arms raised), and remember to use sister sizing when helpful.
