Thanks to Anthro's free shipping policy, I decided to order Le Caprice de Marie underwear which is currently on sale on Anthro's website - a French brand which seemed quite luxurious given that everything was lined in silk. Not to mention the beautiful peachy nude colour seemed perfect - very wearable, but also feminine.
Unfortunately I found the fit to be lacking despite the luxurious materials and nice touch of throwing in extra set of straps. For some reason for both the Balconette and Strapless styles above the underwires tend to dig (unlike tried and true stalwart Wacoal). Even going up a cup size didn't help solve the problem. Also, I think other online reviewers have commented on the generally thin padding.
Verdict: Everybody is shaped differently, so you may want to try for yourself, but I didn't think this brand had a great fit - which is a bit shocking given the original prices on these items. Would rather spend my money on Wacoal.
The briefs were a better choice, and definitely made of lovely comfy, silk blend materials. I sized up to an S.
Verdict: Try the briefs - they are great! They are cut in a modern way - no granny pants here.
