Engineering a chance encounter with Mr. Apartment 3B. Defying the laws of physics with a good brassiere. There’s a science to everything.

Especially when it comes to finding the perfect dress. Which is why fresh-out-of-college Studio 28 Couture creator, Andrea Marron, applied her science major to creating a custom dress builder that lets you design one-of-a-kind frocks online.

Enhance your anatomy in a few simple steps. Start with a flattering top (strapless, bateau, sweetheart). Then choose a ladylike skirt for the appropriate occasion (garden party, picnic in the park). Lastly, pick your fabric and trim from an array of preppy/pretty florals, paisleys, dots, and solids in 100 percent cotton.

Handmade in upstate NY, the expertly tailored pieces have a vintagey feel that will last forever and are sure to attract admirers.

The rest is chemistry.
