40A1/2 Bra Styles at ThirdLove
At ThirdLove, we make sure that women of all cup sizes have a wide range of bra styles to choose from. Currently, we don’t offer 40a1/2 bras as we find that smaller sizes almost always don’t need half cups and find their perfect fit in full cup sizes. We advise you to try sizes 40A and 40B to see which fits you best. If you’re looking for an everyday bra that molds to your breast shape, try our 24/7® Classic T-Shirt Bra. With smoothing sides and ultra-thin memory foam cups, this bra disappears under any outfit, creating a gorgeous streamlined look. If you like lace bras 40a1/2, look no further than our All Day Lace Uplift Plunge Bra. This bra will add more oomph to your outfit, emphasizing your gorgeous cleavage.
How Should a 40A1/2 Bra Style Fit?
Make sure there’s no gaping or bulging when you wear the bra - it should feel snug, but not restrictive. The cups should hug your breasts comfortably and the bra band should sit firmly underneath your bust, flat against the skin. As a rule, you should be able to fit two fingers under the band, so if you can’t do it, it’s time to check your bra size. If your bra straps keep on falling, adjust them and see if that helps. They should sit in the middle of your shoulders without digging into your skin.
