yeah talking about looking more substantial there, I tried one from this bra from a Japanese brand that they are selling at Isetan, called V plunge bra, the effect is good!
Also, for better results, my consultant advised me to start on bust nourishment haha so I've tried Derma (results sort of ok but expensive...), Clarins bust firming gel (not much results at all!), Miraeca (my sis bought from Gmarket online, surprisingly effective and happy with the effects! I look more 'filled up' now hehee but also quite ex). The thing with these creams is that you'll need to massage while applying to really let your boobs get the nourishment haha so gotta be hardworking to see results
