I've never been big on letting your bra strap show. I always thought it looked sloppy and unattractive. And anyway, there's a reason why they're called undergarments. One of my pet peeves is those apparently transparent plastic straps. They've never looked strong enough to hold up a bra, and aren't even aesthetically pleasing, so what purpose do they serve? Another fad I could never understand was wearing a normal bra with a racerback tee. Eew.
But I think I can make an exception with these blinged out bra straps. StrapCouture has a range of pretty straps to attach to your strapless bra, from snazzy metallic chains, to pretty lace straps and straps with precious stones like jade and quartz. They don't come cheap though, the most expensive is US$150, a price which I cannot justify for what is essentially a bra strap. Now I'm wondering if I can just DIY them myself. :)
