28GG T-Shirt Cup Surface Shows Under Thin Fabric

If your shirt reveals a cup line, the cup shape or the shirt fabric may be responsible. Take the shirt off and let the cup sit naturally. A comfortable cup may simply need a different neckline for that particular top. For a more detailed explanation, read our guide to how a T-shirt bra should fit.

28GG T-Shirt Lower Edge Presses While Seated

If the bra feels tighter in your chair, the lower band or cups may be pressing. Sit naturally and check each edge without your shirt covering it. Settle the cups again before you decide whether the fastening needs a different adjustment. Read our fit guide for help understanding how a bra should fit.

28GG T-Shirt Cup Edge Catches Near Your Underarm

A cup that digs near your underarm can be too shallow at the side. Check that the back is level before judging the edge. A different cup shape may give you room without leaving a gap at the top. Our article takes you through why bra cups gap at the top.

Frequently Asked Questions About 28GG T-Shirt Bras

How should I judge the cup surface of a 28GG T-shirt bra?

Look at the cup beneath the top you plan to wear. First settle the breast inside and check for gaps or a digging edge. Then judge the outline from the front and side without stretching the shirt downward.

Does a visible 28GG T-shirt cup edge mean the size is wrong?

Not always, because a visible cup edge can come from your shirt or the cup's cut. Check for digging, spilling or a gap without the shirt first. Change the fit only if the cup itself needs more or less room.

How should the band of my 28GG T-shirt bra sit?

Your back band should stay at roughly the same level as the front. If it rises, the cups may lose their steady position beneath your top. Check the fastening and cup room before shortening the straps.

How do 28GG spacer and seamed soft cups feel different?

Spacer cups have a formed shape, while seamed soft cups use joined fabric panels. Try both with the band comfortable and the breast settled inside. Judge the feel and the outline under the same shirt before choosing your preference.

What should I do if my 28GG T-shirt bra straps keep slipping?

Start with a level back band and cups that hold the breast comfortably. A loose band can move enough to change where the straps rest. Make a small strap adjustment without pulling the cup edge sharply upward.

What is the US equivalent of 28GG?

Our chart pairs UK 28GG with US 28J. Use that pair to read the product's own size guide, since brands can label differently. The cup still needs to follow your shape without digging or a loose corner.
