44O 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 fit article has more detail about how a T-shirt bra should fit.

44O T-Shirt Cup Surface Shows Under Thin Fabric

A cup surface can show under clothing even when the size feels comfortable. Thin fabric can pick up seams or the top edge. Check for gaps or spilling separately before changing size just to alter the outline. For more help with this problem, read about how a bra should fit.

When Your 44O T-Shirt Cup Edge Gaps Or Spills

If the cup edge gaps or spills, check whether its shape follows the whole breast. Settle the breast inside without lifting the cup higher. A different cut can help if the top is loose but the side already feels crowded. We explain the useful checks in our guide to why bra cups gap at the top.

Frequently Asked Questions About 44O T-Shirt Bras

How should I judge the cup surface of a 44O T-shirt bra?

Check the cup's outline beneath your shirt without pulling the neckline flatter. A bra that needs holding in position isn't giving a useful clothing test. Settle the band and cups first, then look at the finish in daylight.

Should I change size if my 44O T-shirt bra shows a cup edge?

Not always, as a seam or edge showing through fabric doesn't prove the size is wrong. Look for gaps or pressure around the whole cup. If those are absent, choose a different finish instead of changing a comfortable fit.

Where should the back of my 44O T-shirt bra sit?

A comfortable band should rest steadily against your ribs and stay level through movement. If the back creeps upward, check the band fit without your shirt covering it. Avoid using tight straps to keep the cups in place.

How can I check the feel of 44O spacer and soft-cup bras?

Spacer and seamed soft cups use different ways of giving the cup its shape. Try the fit on you instead of choosing from the construction name alone. A comfortable edge and the finish under your shirt can guide your preference.

What should I do if my 44O T-shirt bra straps keep slipping?

See whether the strap slips after the band changes position. A comfortable back fastening should help the cup stay put without strong shoulder tension. Check that support first, then remove the strap slack.

What is the UK equivalent of US 44O?

US 44O matches UK 44K on our size chart. Check whether the product uses the UK or US system before choosing its option. Then try the bra's fit, since the same converted size can feel different between cup shapes.
