The waistband decides the fit

The main difference between BABYGO® Under the Bump Knickers and the BABYGO® Over the Bump Thong is where the waistband sits. The Under the Bump Knickers are designed with a low-cut waistband that sits gently under your bump. The Over the Bump Thong is designed to sit smoothly over your bump with light, flexible support.

That single design choice changes how each feels as your body changes. Under-bump styles avoid pressure on the bump and can sit below a C-section incision during recovery. Over-bump styles stay in place with a barely-there feel and may suit you if you prefer light support across the bump.

When under-bump knickers make more sense

Choose the Under the Bump Knickers if you want to avoid any pressure on your bump, especially in the third trimester when the waistband sits gently below it. They are also the clearer choice for postpartum and C-section recovery because the low-cut design sits just below the incision line with no chafe.

The anti-leak, quick-drying gusset adds reassurance as bladder pressure builds. If you prefer full knicker coverage and a fit that stays below the bump, this is the more supportive option.

When an over-bump thong is the better fit

The Over the Bump Thong suits you if you want minimal coverage, a barely-there feel, and light support that sits over the bump. The seamless fabric is designed to stay invisible under clothes, which helps under fitted dresses or trousers. The triple-layered anti-leak gusset gives added reassurance.

Because it is a thong, it offers less coverage than the knickers. The supplied information does not describe postpartum or C-section use for this style, so treat it as a pregnancy-focused choice unless your own recovery guidance says otherwise.

Sizing and pack choices to weigh

The two styles do not share the same size run in the supplied information: Under the Bump Knickers come in S and XL, while the Over the Bump Thong comes in M and L. Check the size you normally wear against each product separately rather than assuming one size carries across both.

Both are sold in 1, 2, 3, or 5 packs. A multi-pack lowers the cost per pair and gives you a laundry buffer, but only if the fit works. If you are unsure which waistband you prefer, start with a smaller pack of each and decide after wearing them through a full day.

What the supplied information does not settle

The product records do not include care instructions, fabric percentages, or a size chart with body measurements. They also do not state whether the Over the Bump Thong is intended for postpartum use. Use the care label on the item you receive and check the size guide on the product page before ordering.
