From the website:
Our form-fitting, sleeveless top design is worked in crochet hairpin lace. Worked in one color or in multi-color stripes, this versatile top is not only perfect for a summer’s day, it can be dressed up for evening, or make the perfect layering piece for any time of year.

Skill level is rated at intermediate, using repetitive stitch patterns, simple shaping and simple finishing.

Finished Size:
Sized in XS (S, M, L, 1X, 2X, 3X) to fit the following body measurements:
Actual bust: 34 (36, 38, 40, 44, 48, 52)“
Finished bust: 31 (33, 35, 37, 41 1/4, 45 1/2, 49 1/2)”

This top has negative ease at the bust because it is meant to fit very closely. The hairpin lace fabric will stretch.

The yarn used in the sample is Tilli Tomas Fil de la Mer; substitute is any dk-weight yarn or to fit gauge.
